All down to budget and driving style. I drive a bit quicker than average but don't make a habit of trying to stand it on it on its nose going into bends (slow in, fast out is what "lift" is for innit??? ) It'll do .....for now......
Sorry, to clarify. New wilwoods about £600
New avensis calipers and avensis discs little more than half that.
Both TSport discs and calipers (& the pads that fit them) imo simply too small to haul the car up quickly, esp repeatedly.
No point replacing Tsport caliper with new Tsport caliper. Fresh discs better the knackered ones ditto pads and when replacing upgrade over standard as a minimum. BUT new vin ordinaire discs pads hoses = 200 (hoses £60 of that). For 400 (with avensis discs and calipers) don't know if you would need new hoses, the performance can be transformed as opposed to slightly improved, allegedly lol.
