Having got used to driving my 85 IROC I have noticed that it pulls slightly to the left. Its not a major problem, its just that my other car is very well set up.

I have checked and corrected the tyre pressures, and have set up the toe in at 3/32" total, and made sure it's balanced. There is no uneven tyre wear etc.

During one of the trips round the block to test it out, and help it settle, I noticed that the pull to the left can be eliminated by driving on the right hand side of the road. In reading all the various posts about alignment I have noticed that the castor angle for the US cars is +0.5 on the right compared to the left. I presume that this is to combat the slope that all roads have for drainage.

Has anyone in the UK had their car converted to have this castor angle change from right to left?

Si.

ps. I've probably got my lefts and rights mixed up but you know what I mean?

 

This is something that I have thought about but my only concern is finding someone to do the job that I feel could do it properly and not make a complete **** up of it.

I wish you luck. Let us know how it all goes.

yea... the reason for the offset is to account for the crown on the road..


flipping the left and right figures should work for ya...


lmao... of all the probs with driving a US car over there, i would have NEVER thought of that though....

 

RMK,

I'm not into getting somebody else to do this sort of thing. I don't trust garages to do even the simple toe in toe out adjustments these days. I haven't ever seen one garage do a good job at it. Actually the last few garages I've been to, couldn't even manage a simple service without getting something completely wrong. All that a garage will ever do for my iroc is the mot.

What I'm thinking of doing is if I can get the measurement side of the job sussed, then I'll try setting it to a castor neutral position, as this is what I'd want if I ever took it to a track day/racing.

I think I'm going to need to get a garage asap, as borrowing my parent's garage is gonna cheese them off soon.....

i believe it is in the camber or caster setting.... mosy UK thirdgens wear the outside edge of the tyres when set up according to the book, even when they are sut up this way....

flip the alignment (left on the right, right on the left, there is a slight difference, and it should be ok..

I'd check with an alignment center though.

 

Been there, done this. Works well.
Take the car to an accident repair specialist. They will have the correct accurate equipment. I was amazed by the procedure!
If anyone wants a place recommended and is prepared to travel to Chesterfield, let me know. About £64 ish I think. And be prepared to be amazed.

Don't even trust garages to do MOT's right,amount of times I have had to go in & show "where the foglight switch is" as it failed on "foglights unoperable", & front seatbacks not locking. This year I went in with a printout explaining the inertia seatback locking system. What a plaster.

Back to your question...IROC-SI, you're absolutely correct on the caster & camber being different here in the UK. Yes, it is all to do with driving on the left & the slope of the road.
