Gone from 14" wheels with 185/60 to 15" with 195/45 in preperation for an upgrade (had hoped to do Wilwood but it's not available anymore). I got the 4 pot Cosworth calipers as a good deal but I know the normal upgrade is the 4WD calipers and Escort RS2000 discs, so may resort to that and resell the 2WD ones.

It's important to keep the contact patch relative to the effective king pin inclination correct, and if the diameter of the tyre has also increased this will be helpful if spacing them out. More likely the diameter of the wheels may have been increased but the diameter of the tyres has remained much the same because a lower profile tyres has been used. Odd handling characteristics can occur, as an example a car manufacturer I've worked for (no name revealed) put large spacers and fat tyres on their 'exclusive' model - when tested on the track and exiting a bend if the steering wheel was released it didn't return to centre but steered into the turn even more! scary stuff. Martin ----- Original Message ----- From: Bob Craig To: [email protected] Sent: Sunday, January 27, 2013 5:29 PM Subject: [Quantum Owners] Brake upgrade Got a pair of Cosworth 4 pots on modified XR2 uprights (bigger holes drilled and tapped for the caliper mountings). Did some basic measurements and they will fit withing the diameter of the wheels but would need at least 25mm spacers to get enough lateral clearance. Not really sure I want to push the wheels out that much due to the effect it may have on handling. I'm no expert on set up so will need to think (and read) about it first. I'm sure increasing the front track will have an effect on handling. As the handling is pretty good, I'm reluctant to change things Any advice appreciated.
