thanks for the replies, the reason im asking about the coil overs is that they change the ride significantly on a 205, making it hard and skitty (if thats a word). Some of the cars ive been looking at have the coilovers, so was i going to avoid them if they made the car uncomfortable.
I really like the power that the 205 has but rarely use it, so power isn't an absolute must.. so if the 190 is sufficient to work with id be happy.
I did have a look at the brake conversion but wondered whats involved, i had a quick read on newcelica and it doesnt appear to be too much work, but i wanted to clarify that. I have a number of 205 calipers and a set of black Diamond and TRD rotors spare.
