Best Camber And Toe For The Rear Of A 205/309 (306/xsara)

[talbotsteve 0]

I'm currently constructing a 4 link tubular axle for the rear of my xsara Kitcar replica, the plan is tu use 307 rear hubs fitted to a tube which will be located using an escort short 4 link set up and astra GpA rated rear coilovers.

 

I will be able to set the camber and toe of the rear hubs when fitting them so wondered as there are more track builds on here that use adjustable set ups what have you guys found works best?

 

Cheers Steve.

quite subjective really, how do you want it tp handle and what tyre construction will you be using?

 

why are you building a non independent beam, effectively a non driven live axle?! surely the standard independent sustem would be superior?

I need the track at the rear due to the Kit car bodykit, currently run 90mm spacers each side and its killing the bearings, I have seen this set up on used to great effect on 205 rallycross cars, its simple neat and very quickly adjustable using a coilover set up, ideal for track/sprint and hillclimbing.

I want to get a good set up as the toe and camber will be the only thing I can't adjust as they will be fixed.

 

I think I will just go with the GpA Astra settings of 0 toe and 0 camber.

0 degree camber!!! Noooooo!

 

Im guessing this is a tarmac car? Even road tyres will appreciate some neg camber.

1.5 degrees neg and 0 toe would be my starting point

Excellent, getting somewhere, I used to run a GpN astra years ago and got advice off Atkinson Motorsport the GMSport Dealer up here in the northwest with regards the GpA set up they used and they ran their cars on 0 and 0 at the back.

 

Cheers Steve.

damn, no wonder they never handled, 205's have over a degree as standard as does your Xsara.

The way its looking at the moment there could be about 10 degrees of camber, not good!!!!!

What tyres do you use and what surface are you running on?

[talbotsteve 0]

Smooth twisty tarmac, not sure on tyres yet, may be 18" ex WRC/GpN tarmac or 17" trackday spec tyres.

got an pictures of said setup?

Toe is a personal preference thing really, i personally like to run some toe in. for trackday tyres (a048/r888 etc) you want to be starting with at least -3 degrees of camber. I currently run -3 at the rear (as do many others) but I'm looking to go to -4 shortly as I'm mainly running slicks.

This is a pic of one I missed recently, was fitted to a 205 rallycross car. A bit narrow but could have been widened easy enough.

sod that

That looks like something fit for the rear of a fwd van and not much else. Are you going to fit leaf springs as well for the full 1940's handling experience?

 

Sorry to be sarcastic but that will be a massive step back from the standard trailing arm setup, and even that has it's flaws. Yes that setup may be easy to fit but it certainly won't be a nice handling car when it is finished.

If you dont want a beam this wopuld probably be your best option:

I do have a budget And its not that good for the whole car let alone the back end!!!

Why do you want the back so wide again?

If you're going to the trouble of completely replacing the rear axle, why not fit a twist-beam off a similar FWD car? If you're careful with your selection you can find one that has superior properties to trailing arms, and will definitely be superior to a dead-beam.

 

Alternatively, commission someone to extend a beam tube for you so you don't need to run spacers. That's probably your cheapest / easiest solution.

If your just after extra width there's also the option of using a 206/clio style bolt on stub axle with a dirty great spacer behind it.

 

Cameron, by twist beam do you mean the swing arm type set-up that ford ka/fiestas use?

Need the track for this.

 

And I don't like these.

I just want rid of the set up on the back as any type of spacing is putting way too much stress on the bearings.

are you on ford offset wheels or something?!

Spacers were fitted when I bought her, and yes ford offset wheels, but pug offset look very mean when fitted. I've given a pair of front arms and driveshafts to a firm to "extend" shall we say but as I'm on a budget these will be done when things go quiet. I had looked at a sierra adjustable set up for the front, but even that needed extended so may as well stay with the std fixings for now. So now I'm looking into what will work at the back.
