Does anyone have any tip to get mer camber on the rear wheels?

A person on the swedish forum are going to test this method.



Cuz my 306 is going to be track oriented, minimum 28,5 ABR and 25,5 torsionbars. And it would be nice with some more camber on the backwheels.

Anyone that got any tips?

You need to machine the stub pin, its the only way you can do it unless you machine an entire new hub assembly. CRF450 is the man to speak to about this. Unfortunately it is not going to be adjustable though, not unless you get lots of different stub axles made.

My touring car has adjustable rear hubs, adjustable for camber and toe, I could get them copied if there was enough demand but can't see a pair coming in for less than £1000 as theres a fair bit of work.

intrigued to see pics of that if you have any, I remember mention of the Eccosse guy's IIRC not being able to drive the Touring car they bought as it was running so much toe out, (it was a bit of a handful...) consequently set to parallel like a ZX tamed it LOL

It's not too hard to imagine if you know what a trailing arm without disc/drum on looks like. Basically a one piece machined stub pin/caliper bracket that bolts to the 4 bolt holes (using seriously strong steel bolts, bearing in mind there are 4 m8 bolt holding the wheel/hub on!). It then uses 2 discs that rotate against each other, turn one to set the camber, then both together to set the toe, or maybe the other way round. Won't be getting pics any time soon as it's a pain to set up so not taking it to pieces.

They ran up to 6mm toe out at the back, it was to get heat into the rear slicks quickly. Tough call really, suicidal handling for 2 laps, or nearly suicidal handling for 10 laps... I span twice in 3 laps at Oulton on cold slicks set at 0 toe, that was under power too, rear slicks just didn't grip...

I run toe in on the back of my FWD cars to get heat in the rears, makes it a tad nervous in a straight line but nothing to worry about. Martin will do a good job on the trailing arms, gives a good amount of toe in and negative camber. Don't use shims as you will get issues with the rear calipers binding.

Gti-6's have 5mm toe in as standard IIRC. Why does it make the car nervous in a straight line? Should make it more stable, and much easier to straighten out a big slide also as the car wants to go straight. Toe out at the back is nervous, you HAVE to stay on the power regardless and cos the wheels are pointing out slides are much harder to catch as if the weight is on one of the wheels only the back wants to go that way. It is faster but you don't half need to be on your toes with it.

Peder- I don't have any pics I'm afraid. I will be doing the tracking again soon so will take some then for you.

gti6 runs less, around 3.5, xsara runs the most, ZX the least at Zero.

I agree it is less stable with toe out than toe in, but in my experience it also makes it a tad more nervous than standard with toe in on the rear especially with cold tyres... Sure it wouldn't be an issue for most regular racers/trackday users, but for someone new to it it could cause concern lol.

Yeah, I ran ZX arms for a bit, the difference was really noticeable. Mainly in the fact that previously I could rcover lift off moments from almost going backwards, but with the ZX arms past a point it was pot luck getting it back. Did improve the turn in though...

Indeed, I used to do it for fun with GTi arms, the most fun I ever had was on the Nurburg GP track in a good inch of standard water on A048's.

Then when I fit the ZX arms it was bad at first but got used to it, but not what I would call fun. The btcc car, well, you just wouldn't bother.
