I seem to have a serious problem with my MY00 UK, when I brake hard at high speed (100mph) the car just won't stay in a straight line, infact its all over the shop and I sometimes struggle to keep in line with the road. It happened yesterday when I was playing with a ferrari as soon as I have to brake hard round a corner the car is a nightmare and scares the life out of me!!!
I should mention that its running with eibachs & bumpsteer plus 18 inch OZs'and has plenty of HKS parts fmic etc...
Is it time to bin the eibachs and get some coilovers or can I tweak the current setup with arbs and drop links etc?????

An easy win would be to check the tyre pressures - get an accurate gauge rather than rely on a petrol forecourt one. This could easily be the problem.
Failing that, sounds like you either need to have your geometry set up checked, or you've got some kind of brake balance problem. I assume by "all over the place" you mean the back end isn't staying in line?

Something like that its difficult to explain as it happens so damn quick, Its just that I have to fight the car to keep it going straight as I hit the brakes hard.
What should the pressures be??

press the brakes on a corner and your bound to go sideways!! But braking from 140mph(on private land) I get brake judder but no sideways action it stops in a nice straight line
Look under the car and make sure your rear brakes are not sticking? then start going for better suspension...coilovers, ive got H&R coilovers and think there quite good.

I think its justs tramlining massively under hard braking. Its only started doing it since I fitted 18in wheels?

My car tends to do this sort of thing too.
Running 225/35 Bridgestones on 18s.
Pity you get the problem with Toyos as they were going to be one of my fixes. Looks like it'll have to be Goodyears.......

The overall rolling radius always changes by some amount when changing wheel sizes. Obviously it's only usually be a few millemeters. Different tyre manufacturers can have quite a few millemeter difference as well. I know this is only a few millemeters but when you are talking about geometry setup a few millemeters can make a massive difference. May be worth getting it checked.
