Negative camber solution

Hi all,

I'm trying to find a way of getting some negative camber on my standard 250 RS as it's appetite for the outside edge of it's front tyres is insatiable!

Thanks to the kind membership here I now know the following are possibilities:
Silver project
Ast
Kw

Are there any others?

Would any members be good enough to share their experiences with any of the above?

I called RSTuning and K-tec today but neither had any suggestions.

Thanks

 

Thanks for this. I'll drop the Kirfel place an email, are these the guys that run the Megane hire cars?

I think you said you are running the silver project ones? Do you run standard suspension with them? What alignment are you running with them and how is it compared to stock with tyre wear and long corners?

Sorry for all the questions!

 

Would you mind saying what you don't like about the design of the silver project ones?

Is there any difference in adjustment and fitting between them?

Something in my confused brain cell recalls fitting top mounts to a car then having the front sit higher than it had been - it raised the car by the thickness of the plate. Is this the case?

Thanks

 

Huge thanks for this - very useful!

When you fitted them did they have any affect on the front ride height?

 

Gent, thanks again

 

Lol and the final question

Do the silver project ones fit with standard suspension?

 

Think it's time for some shopping

Thanks again

 

Thanks chaps for all the help - much appreciated.

I'm quite surprised at how few specialists there are for these cars.

I've spoken to a few different places but none seemed to really know what I'm trying to do or be able to help.

If it wasn't for this place I don't know what I'd have done

Martijn - thanks - I've sent them an email. It seems they've really done their homework on the car.

Also spoke to AST and fingers crossed they'll get back to me.

Jamie - thanks again. I'll probably end up with the silver project stuff.

Really want to get going though, I've booked oulton on Nov 4 then donnington on the 5th staying over two nights.

My track car would probably break before getting there so really hoping to take the Renault.

Need to get wheels and tyres too

 

Thanks for this.

I tried running 36 psi hot on the track but the tyre was rolling over hugely, wearing the sidewall. At about 40 psi it wasn't rolling over as much. I know this is high but it's the only option without running more negative camber.

I got the alignment and all the suspension checked over before putting new tyres on and according to a garage I trust and my feel it's all good.
On track it's excellent for the first 5 or so minutes, then overheats the edge of the front tyre, loses grip, then destroys itself lol (in my experience this is expected from any car).
I run the AST 3 way race suspension on my track car. When fitted it was only running about -1 degree of front camber. It had been running over 2 degrees previously on a much stiffer setup.
This drop in camber (and softer set up) resulted in me killing the outside edge of the tyres in the exact same fashion as the Renault. After increasing negative camber again it no longer killed the outside edge and gave it much more grip
It's my fault for staying out too long but I've never had a car that is so capable at sustaining track abuse!!

Do you run standard alignment?

 

Sorry Jamie, just to clarify you're now running a bilsetin oe type shock and silver project adjustable top mounts? Do you know how much -camber you got with this setup? Do you get even wear?

Love Knockhill, used to basically live there from about 98-2006

 

do you think this may have been because of wheel spin?

 

I think the silver project top mount have castor adjustment too.

 

I got a really helpful response form Madeno:

I'm sorry we don't have top mounts for the original suspension, the OEM springs are too wide
and there is not enough space to adjust the strut inside the front fenders. It's only possible
with lineair ID 60 or 65mm springs together with a sport suspension kit.

we recommand the eccentric front lowering arm bushings and the adjustable caster bushings
from powerflex ( the purple ones, black ones are too stiff ) to gain more camber and caster
work perfectly with OEM suspension

I don't want to have to change the bushes in the arms but interesting to see them saying the powerflex solution works perfectly. Also that there isn't enough room with the stock spring for adjustment.

Do you think adding more than -1 degree will mean you have this problem?

 

That's way beyond my understanding but I'm impressed

 

I got word back from AST that they definitely do the top mounts for the standard suspension and have stock.

Although it would be the most expensive, getting the AST's would be easiest. My local garage can supply and fit then I wouldn't be gambling the possibility of labour costs if I had issues.

Just wondering if there is anything else I should change whist getting the top mounts put in?

This will be the second time I've paid for alignment in a month so keen not to do so again!

 

Going ahead with the AST top mounts.

Also got some AD08R's 235/35/19 for £105 each. Fappin bargain and good reason to stick with 19's for the time being.

Finger's crossed these new boots will last better!

Will report back once fitted

 

Just a few days I think. Mine are being fitted this week.

 

Just dropped it off at the garage.

Had a quick chat to the mechanic and he was saying how good the Megane is.
He advised it might be worth using some shims as well at the back to adjust toe and camber. This will encourage it to rotate more - it's pretty good already

Hope this doesn't mean I get black flagged for drifting every track day lol.

Should be done middle of next week but not sure when I'll be able to test it.

Will come back with it's new AD08R's fitted.

Happy days
