Wed, 13 August 2003 22:52 Thats all well and true however theres always an exception to the rule... AE86's for example love extra track.. it seems they were designed with just a tad too little track! adding 20mm each side front and rear does WONDERS for the car, sure it may wear out things a little faster (i've never been able to measure the rate of wear so i wouldnt know) but the handling, stability and controlability provided is simply awesome! S GIN51E wrote on Tue, 12 August 2003 19:23 Just buy rims with the correct offset, you don't want to fuck around with your wheel track otherwise you stuff up your scrub radius angle, if you move your center line of your wheel further out from the car you may get to the point where you get a negative scrub radius angle which is bad, what that means is under hard breaking "heavy load" the wheels will get a toe out effect which mean it makes the car unstable under hard braking and if you then chuck in the effects of a brake failure so only one front wheel actually brakes then add that in with toe out and you have a very unstable car and good luck keeping it on the road. RTA has specs and they are actually there for a reason, you increase the track on your car and you then put more load on bearings and pivot points ect, i actually think the most your aloud to increase the track on the car is by 25mm and thats not 25mm on side its a total figure so the most you can move a wheel's center line out from the hub is 12.5mm the reason the RTA came up with this is cars probably have to come out from the factory and be able to run 25mm wider track while still remaining a GOOD " " positive scrub radius. Mercedes benz wanted to put larger brakes on their new cars but to do so they had to move the wheel further out from the car which then meant they now had a bad negative scrub radius. now to overcome this they had to come up with a three link front end design so the front wheels now had 3 control arms. a lot of testing and design goes into a cars suspension set up and angle, and if you start fucking with those angles then you will begin to loose out on handling and safety. and increase wear to other components. wheel bearings are designed to withstand a certain amount of load for the vehicle you move the center line of the wheel further out from the car and you are now placing more load on that bearing reducing its life maybe even to the point of sudden failure. you may think moving your wheel track out a few cm's not to be that big a deal but when you think about toe-in toe-out meassured in only a couple of mm's and camber usually talked about in 1-2' then i think a couple of cm's would make a rather large differance. don't be a tight arse and buy 2nd hand rims with the right stud pattern go out and buy some wheels with the corect offset, and everything else.you can increase your tyre width without affecting your wheel track. and if you are doing a complete custom job to your car and have to mess with the wheel track and so forth then do a few calculations and modify other elements of the suspension the car will still handle good and remain safe.
