Crazy Cat Lady Posted October 11, 2015 Report Share Posted October 11, 2015 (edited) Next Friday my Gen7 is booked into a performance specialist for: 4 wheel alignment [Full Geo Set-up] & coilover set-up plus corner weighting. However, i'm getting second thoughts on the corner weighting, apparently it's time consuming so costly per hourly rate, and i don't intend to track or race ever, just normal ~ brisk road use. but is it still worth doing just the once to set up my recently fitted coilovers? BC Racing [bR type] fitted 3 months ago Thanks for any advice Debs [ Edit: service amended to not bother with corner weighting ] Edited October 11, 2015 by Crazy Cat Lady Link to comment Share on other sites More sharing options...
toiletduck Posted October 11, 2015 Report Share Posted October 11, 2015 Total waste of money, imo. Link to comment Share on other sites More sharing options...
splinter Posted October 11, 2015 Report Share Posted October 11, 2015 For a road car, total waste of time. Full geo set up is all you will need. Link to comment Share on other sites More sharing options...
Crazy Cat Lady Posted October 11, 2015 Author Report Share Posted October 11, 2015 For a road car, total waste of time. Full geo set up is all you will need. Thanks for that, ...is full geo set up the same as 4 wheel alignment? There is time for me to phone them up tomorrow and cancel the corner weighting job on Friday.

Bumblebee Posted October 11, 2015 Report Share Posted October 11, 2015 as said above , get them to set the ride height and a full geometry set up and you will certainly notice the difference . Corner weighting only really comes into its own out on track Link to comment Share on other sites More sharing options...

Sherv Posted October 11, 2015 Report Share Posted October 11, 2015 full geo setup will include camber and toe adjustment as well.I have the same coilovers as you, they set the exact ride height that I wanted then wheel alignment front and rear and camber and toe, I have adjustable camber on the rear so it was all of it bar corner weighting.Had it done at Westfield in Essex, was around 105 quid Link to comment Share on other sites More sharing options...
lb423 Posted October 11, 2015 Report Share Posted October 11, 2015 (edited) Yes it usually means the same from my experience, do you know what system they are using for the 4 wheel alignment? If it's the Hunter system it will include all geometry settings, toe, camber, caster. Also as above, no need for corner weighing unless you are tracking the car. You will only really notice the benefit if you are cornering on the 'limit'. If it is corner weighted then the 'limit' would be the same for both left and right hand cornering, assuming everything else is set perfect. More worth while on rear wheel drive cars, as it allows for more predictable drifting. Edited October 11, 2015 by lb423 Link to comment Share on other sites More sharing options...
Crazy Cat Lady Posted October 11, 2015 Author Report Share Posted October 11, 2015 Thanks for replies, guys. Have emailed them to amend my appointment to full geo & coilover set up. .......do you know what system they are using for the 4 wheel alignment? It looks like: Haweka BD Perfromance in Wrexham: http://www.bdperformance.co.uk They sell various makes of coilover to include BC Racing, i'm pretty sure they'll understand what it needs to get it sorted. They are only 20 miles up the road from me, i'm really looking forward to going next Friday Debs Link to comment Share on other sites More sharing options...
lb423 Posted October 11, 2015 Report Share Posted October 11, 2015 Yea thats pretty much the same system. You should get a printout like this; 1 Link to comment Share on other sites More sharing options...
Crazy Cat Lady Posted October 11, 2015 Author Report Share Posted October 11, 2015 Nice print out picture - looks like it needed more negative camber & some alignment. It's very interesting, clear and precise of what you had, and what you got! I'm hoping they won't have any agro with seized up rusty adjuster bolts :rolleyes: Link to comment Share on other sites More sharing options...
lb423 Posted October 11, 2015 Report Share Posted October 11, 2015 Yea mine was way off as I had just rebuild the entire car [emoji1] Yours shouldn't be as far off as that, and yea it definitely help if there are no seized bolts as you will get charged an hourly rate to make any adjustments. It's a very impressive piece of kit, and very accurate. Are you just going to get them to it set as per the Toyota specifications? Link to comment Share on other sites More sharing options...
Crazy Cat Lady Posted October 12, 2015 Author Report Share Posted October 12, 2015 I wouldn't know what to suggest as to alternative spec, although i'd think the ride height lowering is going to affect it. I like where the height is now [about 35mm] which isn't to radical. Is the Toyota spec set up okay to go by? Link to comment Share on other sites More sharing options...
lb423 Posted October 12, 2015 Report Share Posted October 12, 2015 Yea the Toyota spec is perfectly fine to go with, especially if it is just for normal road use. I decided to go for a little more negative camber to provide increased grip when cornering. By lowering your car this will have increased negative camber, which they will adjust back to the Toyota spec unless you tell them otherwise. One thing that might be worth checking is that they are using the correct figures. They will enter your reg into the machine and it should come up the figures as per the Toyota workshop manual. I'm sure someone on here will have a link to the manual..? Link to comment Share on other sites More sharing options...
Crazy Cat Lady Posted October 12, 2015 Author Report Share Posted October 12, 2015 If the Celica GT is 30mm lower in standard spec...? and if it has the same chassis & running gear..? would it be okay use GT spec? Probably worrying too much about this, the guys at BD Performance are used to fitting coilovers and set up, i bet they'll know what's best. Besides, i'm half expecting my rear camber adjustment bolts to be seized stupid solid so may have to settle for a compromise geo. Debs Link to comment Share on other sites More sharing options...
GreyRacer Posted October 12, 2015 Report Share Posted October 12, 2015 a little more camber on the front will be OK. If I remember Toyota is -0.75 and I run mine at -1.3 Link to comment Share on other sites More sharing options...
Crazy Cat Lady Posted October 18, 2015 Author Report Share Posted October 18, 2015 (edited) Update: Attended the full geo & coilover re-setup on Friday, but things didn't go strictly to plan. The first problem was [and still is] the total seizure of camber adjustment bolts at the rear, so on this occasion no adjustments were possible for the rear-end, although this sadly was more or less what was expected, it's seems to be a common problem voiced on this forum. Apparently the front-end was also problematic with corrosion and some time was needed to loosen up tight track rod ends, but apparently this was achieved. The second may or may not be a problem, but a difference of set up procedure with the guys at BD Performance, they routinely setup coilovers up by corner weighting. They don't actually add weight in the form of ballast anywhere, it just seems to be an alternative way of setting up the suspension; to the claim of improved 'drivability'. Out of some debate and consideration [ these guys are coilover stockists who fit coilovers regularly so one would assume they have a set-up strategy that works ] i decided to allow they to set-up my coilovers the way they usually go about it. The results of 3.5 hours of labour [ totalling £189 ] has produced lighter and more predictable steering, more agility, comfy-wise it isn't a world apart than before but it has improved enough for me to experiment with increasing the damping from 3 clicks to 8, they must have slackened off some excess pre-load on the springs, it is slightly more comfortable, body-roll very slightly more than before but still very acceptable. The ride-height appears to have lowered slightly at the rear, may just be aesthetic but i don't like how this presently looks - i need to get on it level ground with a tape measure later and get an accurate measurement. The handling improvements are very welcome but i wonder how much more could be gleamed with a good sorting out of the seized-up rear end, easier said than done unfortunately. The alignment results printout figures have me completely intrigued, but i can't say i understand them, some of this due to no black ink in their printer so there's no titles or terms to what the results figures actually are, but the figures kind of correspond to typical 4 wheel alignment formation diagrams so they can still be seen in the colours green and red, but the figures themselves look rather excessive to me. Will photo this printout and post it here later : ) Debs Edited October 18, 2015 by Crazy Cat Lady Link to comment Share on other sites More sharing options...
Crazy Cat Lady Posted October 20, 2015 Author Report Share Posted October 20, 2015 The alignment results printout i was handed on Friday after the job *note: no black ink in the printer These figures don't look final to me... i've asked them to email me the full results Link to comment Share on other sites More sharing options...
Insanity-74 Posted October 20, 2015 Report Share Posted October 20, 2015 A friend of mine had his car fully set up by a similar company, corner weighing etc, cost nearly £300 in total but the difference was outstanding. The Car was a Toyota MR2 with a v6 or v8 conversion (I cant remember which?), it went from a twitchy, nervous & unpredictable driving car to something that felt well planted and a pleasure to drive, the difference was like night and day. Its definately on my list of things to do when my project build is complete, in fact after getting it mapped it will be the very next thing I do. Also Andy (Redbeast From The GT4OC) had the same thing done to his RS200 Kit car, funilly enough also a Toyota MRS with a v6 conversion with the same results, I think it cost him slightly less, about £250 if i recall. But he had tried all sorts of things to improve its drivability, tyres, tyre pressures, tracking, different suspension, coilovers, non coilovers, the list goes on.The full set up completely changed his car. 1 Link to comment Share on other sites More sharing options...
Sherv Posted October 21, 2015 Report Share Posted October 21, 2015 I didnt have corner weighting done on my car but id had Whiteline adjustable camber bolts from GTFour play on the rear to go along with the polybushed Whiteline ARB, and the BC BR coilies on.I had a full geo done for about 105 or 115 quid I think and the car was night and day from an OEM setup.See what your proper printout looks like because what you have is a little naff without the basic info Link to comment Share on other sites More sharing options...
