And I'm sure you are 100% correct - and ordinarily I would agree...........with a stock vehicle. Yes, I'm using 'o' ring seals - yes, the brakes are in good condition, - yes, using good pads (Hawk HP Plus) However with 50% more of 'everything' braking inadequacy (certainly for me) is still an issue. I remain to be convinced that some of the aftermarket 'big' brake options on the market are a significant and worthwhile improvement. Even in the 'States the best you will get from anyone who has used ab altermative is "great brakes, work well bla, bla, bla". No one individual or company has actually measured and compared stopping distances etc. I'm certainly not prepared to shell-out 3 or 4 £K in an attempt to significantly improve my brakes based on comment like "great brakes, work well" etc etc
I have a friend here who is currently changing the original brakes on his '72 for a Wilwood set-up, 6 pot fronts and 4 pot rears, with new rotors (all round I think). He enjoys track events and reckons the new brakes will be a big improvement. I'll be very interested to see what he thinks. While I doubt I'd make the change, certainly not to 6 pits, the Wilwood callipers are lovely bits of kit!
