I respectfully disagree - there are plenty of lowered (147/156/GT) cars with or without upgraded brakes that are fine with the standard uprights camber wise and I didnt notice much of a difference with inside tyre wear between the standard and GTA uprights. Plus the 166 Brembo route is lighter than the GTA upright route, saving on unsprung weight.
I would prefer that the brembo in the 166 be a viable option as it is MUCH cheaper to accomplish than the GTA conversion and the Punto/Mito brembo..these are just horribly priced at around £800..!
if brackets are available and it can be done without too many compromises I would happily do it, I have been advised that it requires a fair bit of fettling to get them to fit including both brackets and spacers and there may be some issues with the calipers being central.
honestly my knowledge is limited on this as I have no experience of brake upgrades beyond kits designed to do the job or fitting better pads/discs/fluid and braided hoses...as far as mixing and matching components from other models i would not know where to start.
I have come as far as I can with my stock calipers having fitted performance pads and fluid..only discs and lines now can be upgraded and the improvement will be minimal. The biggest issue is the cold performance of my current pads so I will be fitting EBC yellow stuff to see if this will give me a wider range of efficiency, I am aware I may lose a little ''hot performance'' but am happy to sacrifice this for better all round ''grab''
I am off to both Loz and Ned this week for some VNT tweaking a GTA clutch and SMF conversion and a ''final'' map, I expect to be around the 250 BHP mark and the brakes WILL need addressing...this hybrid is bl**dy awesome..!
any suggestions you have will be much appreciated, especially regarding the parts and procedure required to use the 166 calipers.
