Thicker ARB's are not a waste of money on a road car IMO. The reason TGM can leave the OEM Honda ARB's in place in their race cars is because they're race cars. With all that weight stripped out, they have no need for thicker bars to counter body roll as there'd be a lot less body roll in a stripped out race car. Aswell as that their cars have cages which will only add to the rigid feel of the cars
actually they arnt much lighter than road cars due to all the extra strengthening, cage etc, they are of course stiffer but again, the dc5 is stiff to start with and that doesnt affect the need for an aftermarket arb, , also the TGM cars are used for endurance racing, so being superlight doesnt help they need to be solid to last the distance,
unless you could half the bodyweight you will still get considerable roll, but as Paul rightly says once you have a stiffer spring the roll is reduced antway, hence why Tom says its pointless, and i would have to agree with that, even on a std dc5 i wouldnt bother as i dont believe there would be any gain, the chassis is already well sorted from the factory, go and drive an astra vxr and you wont be worried about arb's on a teg.
