Anti roll bar

Just wondered if there has ever been a front anti roll bar upgrade available? I was looking at it today and it really is puny, looks like it belongs on a Nissan Micra (or Smart car ). Even a poly bush kit would help, but I dont believe one is available.

Ive looked into polybushes, id need to order around 500 for a batch to be made (but this would be rear only as they are all the same bush, fronts are a different matter), but truthfully the Renault bushes are fine.

The A610 antiroll bar is thicker, but it is a far heavier car.

I think Paul Sage told me that Iain Black runs his race car without a roll bar, for some reason, better handling I think.
Iain, is this right? any comments or suggestions?

Front or rear? Stiff roll bars can cause a wheel to lift on hard cornering, but its normally sorted with stiffer springs.

I can confirm it does run with no anti-roll bar at the front. Is on mildly lower suspension and 7 and 9 x 16 wheels I think. And Konis I think

Why no rollbar? Presumably its to decrease understeer....but I havnet really experienced that with the GTA.

You may find a bigger effect in upgrading the rear bar... that is where the weight is after all. As far as bushing is concerned Transautosport will usually make up small batches of nylon bushes if you take responsibility for the measurement. (If you ask them nicely)

Someone at the event on Monday commented that my car looked like it was diving, and it felt a little too roly poly! I will be winding the shocks up a click of stiffness to see if that improves things first.

The problem I found is may firms can make the 'soft' part of the bush easy enough, it just became more hassle due to the fact the GTA bushes are steel cased, and this is far more work and more costly to manufacture.

Can I add anything to the debate when everybody seems to know more about my car than I do?

Anyway here goes, 10 years ago the car was fitted with 610 size wheels/tyres with 40mm drop springs and MECA competition dampers (the fronts rubbed away the inner wheel arches). In my opinion the understeer was excessive on the slower sprint/hillclimb tracks and I contemplated removing the front roll bar (must have read about the solution in Triple C mag) and stiffening the rear.

However, a visit to Ashford Motorsport to investigate bigger brakes to replace the warped/cracked Black Diamonds prompted the comment “bet the understeer is terrible on that” and a recommendation to jack the car back up.

25mm (Prima) springs all round followed – still not happy, LEDA 20mm drop at the rear – slight nose down stance – better, replaced MECA dampers with standard front and Koni adjustable rear (not the hardest setting but untouched since fitting), replaced front Yoko`s with SO2`s – finished.

In my opinion the car is more chuckable now with reduced understeer in the slower corners and the suspension as hard as I want it to be for a road car .

In conclusion – 25mm drop at the front (rate unknown), 20mm drop at rear (rate unknown), standard front dampers and Koni rear (setting unknown) but as far as I know, it still has the front roll bar but will ask ARR to check next time they are under it.

Told you I would`nt be able to help

None the wiser!

I have a similar solution hence why I dont suffer much understeer. My front is lower than the rear and has stiffer springs, although I have Konis all round.

The Europa cup GTA had a smaller rear bar (17 mm) and a thicker front one (I believe 23 mm).
