Tony Posted July 20, 2015 Report Share Posted July 20, 2015 What sort of mods does the car have, suspension/ bushings/ wheels/ tyres and so on. Quote Link to comment Share on other sites More sharing options...

Tony Posted July 27, 2015 Report Share Posted July 27, 2015 Have you had any past measurements made? Reason i ask is the front camber adjusters are very limited meaning the rear has to be set in accordance to apply over/ understeer. Quote Link to comment Share on other sites More sharing options...
petrolhead Posted July 27, 2015 Author Report Share Posted July 27, 2015 Just recently got the car so nothing done. Pins still in strut top mounts Quote Link to comment Share on other sites More sharing options...
Tony Posted July 28, 2015 Report Share Posted July 28, 2015 Once the pins are removed it allows about +-30' of camber adjustment so at max i assume you will have about - 1 degree. The OEM rear camber is about -1 degree 50' so it wouldn't be wise to advance that because it would reduce the tyres contact patch. This all means all you really have to play with is the front/ rear toe angles. The toe angle is a compliance angle meaning any static reading is lost dynamically so if for example we have +20' static toe in on the front then once the bushings take the loading under thrust you have a calculated 0 dynamic toe. This is true for all cars whatever type of drive they have. Reducing the front static toe position increases turn-in but can make the car feel unstable at speed Increasing rear toe-in adds tyre temperature and adds ease to power-steer but can make the rear snappy off bump corner on/ out. Toe has a weak force so a value of -30' total front and +50 total rear is sufficient to feel as a driver but not so much you have to adopt a defensive position. Failing all you can buy adjustable front top mounts which will open the geometric door. Quote Link to comment Share on other sites More sharing options...
