Cup car suspension

First post!

Hi guys been told this is a good lace to ask this as you guys are renault geniuses, so can anyone tell me how the megane mk1 cup racers used to set the rear of the car up suspension wise?

I have a set of cup racer struts which are an adjustable damper and spring setup like a coilover.

The rear of the megane is a torsion bar, which is the spring on the standard car, but with this cup setup one of the springs (torsion bar or coil spring) is going to be useless. Does anyone know what the cup racers done with the torsion bar?

Cheers

I'll ask one of my fiends who has a Megane cup car, it competed in the Dutch touring championship and I think it is still in original trim.
Off the top of my head I think it uses the coilover as a supplementary spring on top of the torsion bar spring rate.

[Matt@CodeRedMotorsports]

Right, he has the Tarmac type setup from a maxi Megane. This would have used a different beam, it has no torsion bars. Needle roller bearings and a Coilover damper setup.
I'll get a pic up in a mo.

Here you go.
Hope this helps.....

Technically I should delete/move this thread as the OP is a non member....

But instead I will lock this thread... as I very much dount the OP will have any interest in joining RTOC..... despite getting his answer within 2 hours...

Jaff, join RTOC, for the £25 you will get access to alot of technical info & we would be interested in hearing/seeing more of your car.

Welcome to club Jaff.... Best £25 you have spent

Ha thank you. Must admit £25 is a hard pill to swallow and I have been putting it off for a year or so now. But needs must and I'm here now

Matt thanks for those drawings, I hope there is a variation in the cup cars to the maxi cars (there will be in track width anyway) as I don't fancy my chances at finding a maxi rear beam, then cutting it down!

Anyone else got any info that's more related to the cup car? I have a picture of the strutt if it helps people help me come to a solution...



More info on the car when I get my project blog copied over here

Anyone able to help? Cant find nothing online

might have had one end of the torsion bars splines machined off, hence removing their spring effect - then with uprated damper mounts use a coilover as a conventional sprung damper.

The torsion bar would need a jubilee clip or a means of retaining so it doesn't fall out.

You can run coil overs with the OE torsion bars still in place Even on other smaller renaults...

And the ARBs too. You will rob ably find the dampers matched to suit the additional spring rates.

So keep the bars in then?

Was hoping this was a solution to get rid tbh lol never mind!

Blog is up on here too btw
