Odd sized spacers.

[The cape]

Hey guys,

Just need some advice on wether or not I can use odd sized spacers on the rear of my 2004 boxster. It has had some body modifications which means that I need to use a spacer 10mm thinner on the rear right compared to the rear left. Clearly this is not ideal but do you guys think this is dangerous or might cause big issues? Or would it be ok?

Cheers.

I assume the body is asymmetrical for some reason.

Making the suspension asymmetrical to suit it is a bad idea. 10mm is not enough to cause any major vices but it is still a bad idea. Better to either fix the bodywork, or live with it as is.

You can’t just ask that and then leave it there.
Please let us know why you need different size spacers.

I'd say that you shouldn't do it. Making one side 10mm thinner will alter the whole geometry of the car.

I'd be wanting to find out why things are so bad in the first place, and having a full geometry and chassis check in case something is bent stupid.

Hey guys,
Thanks for the responses. The chassis alignment/balance is perfect(been checked). It’s a bodywork issue with some aftermarket flares that are slightly misaligned and will now be near impossible to readjust as bodywork/paint is done.
So my only option (as I see it) to stop the wheel rubbing and to look correct relative to the bodywork is to inset it very slightly. There’s currently a 30mm spacer on each side and the plan is to leave it on one side and replace the other (which rubs) with a 20-25mm spacer.

So the end result would be correct geometry but with a 5-10mm difference in spacer width from L rear to R rear.

So, my Qu is... would this 5-10mm difference cause an issue?

Cheers.

No. But it's a fugly bodge.

Sounds like a bad idea to me.

No, the end result would be completely incorrect geometry.

Outer bodywork does not dictate how chassis geometry is setup !

If you read my post I already acknowledge this.

First off you will only be able to see the difference either side if you are related to a flat fish
You know it looks different no one else will.
Offsetting one rear wheel in relation to the other 3 is not a good idea but if your just concerned with how it looks just don’t get to enthusiastic with your driving.

Thanks guys. I appreciate all the advice.
