Why are there no options for a thicker front anti roll bar?

[shiyan]

We all know there's the whiteline rear anti roll bar, which I have fitted, but why has there never been an option of fitting thicker front anti roll bars? Yes some body roll is well and good but once on semi slick tires the body roll is just massive, and really makes quick direction changes a lot more difficult as it always takes some time for you to go from one extreme of body roll to the other. Meanwhile the corner's already arrived and passed. I've had to resort to braking between direction changes as a result. Harder springs can cure the problem somewhat but there are other consequences of doing so.

Anti roll bars are a very common modification on other cars, and judging by the changes made to the 197/200 Cup, even Renault themselves have fitted thicker front anti roll bars to reduce the amount of body rolll.

I see you've got a phase 1? Could always try the 182 front roll bar as their a bit thicker (1 or 2mm) than the 172's i think??

Will this not just encourage it to understeer?

Think this is why there's no after market ones!
But if you've stiffened up the rear a lot ie with a whiteline arb and its tail happy the front ill help a bit i suppose to make it more neutral again

There are uprated front ARBs available.

But stiffening up the front will result in understeer.

More understeer yes but more grip as well. Cup cars have adjustable front ARBs

 

[mr.pink87]

Cup cars are normally running slicks aren't they?

Oh cool will look into this.

Yes but with the adjustable rear anti roll bar I'm currently on almost the softest setting, so I have some more adjustability left to compensate for a bigger front anti roll bar.

Wow thanks so much!

I take it you talking about 200's as my 172 cup racer doesnt have an adjustable ARB.

 

[Sam@NP]

^ yep.

what suspension are you running?

 

[shiyan]

what suspension are you running?

KW V2

KW suggested slightly harder front springs, I might give that a try if it doesn't cost too much.

 

[Cupman29]

Think I'll try harder springs on my V2's for this reason.

All clio 2 RS (172-182-Ragnotti-cup),front antiroll bar,25mm!!!

Me too:approve:!!

what rear setup are you running with the firmer front springs?

 

[shiyan]

what rear setup are you running with the firmer front springs?

I'm not on the harder front springs yet. I asked KW if it would be a problem only changing the front springs (they don't have harder rear springs for the V2) and they assured me that it would be ok.

[FONT=Times New Roman,serif][FONT=Calibri,sans-serif]Hello,[/FONT][/FONT]
[FONT=Times New Roman,serif][FONT=Calibri,sans-serif] [/FONT][/FONT]
[FONT=Times New Roman,serif][FONT=Calibri,sans-serif]unfortunately, for the rear of this car, we do not offer harder springs.[/FONT][/FONT]
[FONT=Times New Roman,serif][FONT=Calibri,sans-serif]After discussing with our motorsports department, they confirmed, that with new springs on front axle and the same springs on the rear (as they have been chosen to be quite “firm”), you should get a good result on handling.[/FONT][/FONT]

You could always stiffen up the rear by setting the arb and rear shocks firmer. So should be fine i assume.

I thought these were already perfect out of the box?

one of the best you can get, and they're "not too soft for track" utter rubbish, people see to think roll is a bad thing, its not!

 

[shiyan]

Depends a lot on the tires you use. If you stay on road tires they're close to perfect but once you move on to semi slicks then the combination of the standard anti roll bar with the KW V2 is too soft. Even KW admits that if you read the email.

That doesn't mean the V2 isn't a great product, for the vast majority of buyers it's a great compromise for road and track use. It's only the small minority of V2 buyers that track their cars very seriously on semi slicks for whom the standard V2 springrates are not sufficient.

All coilover sets are a compromise. More track focussed ones are more harsh for road use. The V2 strikes a good balance for most.

Lol, my comment was a little tongue in cheek Shiyan. I've come to a similar conclusion with my ASTs & am similarly upping the front spring rate
