		Ive been using fondmetals and cyclones on track but Im yet to delve into light weight alloys. Id try the TDs but they just seem pretty common. If you do get some make sure you get them in a proper pug offset and not the ford ones with spacers which are more common. Id expect acceleration and braking to be better as there is less rotating mass to stop and start.

		Nice shout about the offset! I'd have probably not even remembered that!
I haven't heard of Fondmetals. Are they light or just about the same as standard cyclones?

		There is a number of benefits to reducing weight on a wheel/tyre assembly. Principally that is the reduction in rotating mass, and the need to accelerate/decelerate that mass (think why people fit lightweight flywheels). The rest of the benefits revolve around less force into the suspension from a bump or undulation, and less disturbance/effect on the tyre's contact patch - how quickly the spring can return the tyre's contact patch in the event of a dip, how little it varies is how much you can exploit what's available, which in racing could mean a greater corner speed....
I would advise you go and read about sprung and unsprung weights.

		also gti6 brakes definitely dont fit under 4000s. Some 266s may do but others need the caliper grinding down to clear. :/

		loads of space for big brakes.
not quite as much as a full on motorsport wheel but close.
