toyotasuprauk Posted November 21, 2008 Share Posted November 21, 2008 My car isn’t handling right. It will drive and brake straight on a dead straight level road. However if the road points to either the left or right the car seems to want to follow the road. Going downhill on a road that’s slopes to the left for example whilst braking in traffic the car is really pulling to the left. I had my brakes checked and the garage replaced the calliper pins, cleaned them out etc but it still wasn’t right. I got the alignment done but not successfully as some of the nuts were seized so I need to get that sorted first. Camber (I think) was well out on both sides but it was even so they said it might have been set like that previously so at the moment they are both at -3 from memory. Any thoughts? Could it just need the alignment sorting or could this be a suspension issue? Also since I went from 16” wheels to 18” the problems got MUCH worse.

Dnk Posted November 21, 2008 Share Posted November 21, 2008 3 degrees of negative camber is way too much and youll get through tyres very quickly. If the camber adjusters are siezed like mine were then they'll probly need to be cut off and replaced, you could have buggered lower arms as well if the adjusters are also siezed in the lower arm bush's which 2 of mine were.

Nic Posted November 21, 2008 Share Posted November 21, 2008 (edited) Wrong offset wheels, suspension component wear or alignment, it could be any one of those. Get the suspension components checked by a specialist and get the alignment sorted.

In case you didn't already know, what you're describing is called tramlining, and cars with wide tyres do this anyway. All Supras do it. Those with bigger/wider wheels do it more. Wrong caster angle would cause this too (think how a shopping trolley pulls its front wheels around instead of pushing them).

carl0s Posted November 21, 2008 Share Posted November 21, 2008 Or at least I think it's called tramlining anyway ,even though you're not driving on truck damaged/tramlined roads. Quote Link to comment Share on other sites More sharing options...
Wez Posted November 21, 2008 Share Posted November 21, 2008 You went from 16" wheels to 18" wheels. What size tires did you use to run on the 16s and what are you running now? Quote Link to comment Share on other sites More sharing options...
toyotasuprauk Posted November 21, 2008 Author Share Posted November 21, 2008 On the 16" stock wheels I think the front was 225 and the rear size was 245. On the 18" on the front 245 and back 265. It still did this a bit on the 16's but nothing like I remember it now. Quote Link to comment Share on other sites More sharing options...

toyotasuprauk Posted November 21, 2008 Author Share Posted November 21, 2008 I'm running 36psi in both the front and rear. 235/35/18 fronts with goodyear eagle f1. Rears 265/35/18 Falcon 452's. Size from memory. Its an Sz-r with the blisten shocks. Quote Link to comment Share on other sites More sharing options...
Guest sundog Posted November 21, 2008 Share Posted November 21, 2008 If you want the big wheels your going to have to live with this,Same happened to me,you cant get away from the tramlining with wider tyres, on some roads it gets bloody annoying just make sure the camber is right and theres no wear to the suspension etc. Sundog Quote Link to comment Share on other sites More sharing options...
carl0s Posted November 21, 2008 Share Posted November 21, 2008 Maybe lower tyre pressure up front will help the tyres take up some of the side pressures. Quote Link to comment Share on other sites More sharing options...

gordy07 Posted November 23, 2008 Share Posted November 23, 2008 The 18s wont help at all mate i had the same problems on previous cars SRIs,XR2s etc Quote Link to comment Share on other sites More sharing options...
botachi Posted November 24, 2008 Share Posted November 24, 2008 Tires might also be knackered which is why your tramlining is worse than usual. I run 265 fronts (285 rears) and it's just as bad as Porsche GT3's and the like with narrower front tires Quote Link to comment Share on other sites More sharing options...
toyotasuprauk Posted November 24, 2008 Author Share Posted November 24, 2008 Brand new tyres on the rear and about 6mm on the fronts. When it goes in for a service I'll get all the alignment done and go from there. Hopefully that will make a big difference. Quote Link to comment Share on other sites More sharing options...
Ian C Posted November 25, 2008 Share Posted November 25, 2008 I have exactly the same sized tyres, and when the pressures are right and the geo is set properly it doesn't tramline. I despise tramlining, it ruins the fun of the car. There is a thin line between "feeling the road" which is where you should be and "constantly holding the wheel straight against a left or right impulse" which is tramlining. Very noticeable on roads with channels worn in them by lorries. You've already said your camber is off and the suspension alignment wasnt done right because nuts are siezed. Guess what your first step is to curing the handling issues -Ian Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted November 26, 2008 Share Posted November 26, 2008 You can't get -3 degrees negative camber at stock ride height, there's not enough adjustment, so I suspect the car is also lowered. Lowering adds negative camber. I'd put it back to very near, or at, stock ride height, get the full geo done, and post up the wheel offsets and whether you have wheels that fit the hubs without the dreadful spigot rings wheel sellers bodge things with. If you have wheels that don't fit the hub noses, and don't even have spigot rings either, then the thing's a death trap. Search on broken wheel studs...
