y would u bother welding ...
just get a set of rice pedals throw them in, will fix the gap thats what i've always done, ebay under $20
i learnt heel n toe by accident on may way to work there is a down hill bit corner than a steep up hill and u need as much speed as possibly to get up and when it rains water pools mid corner (bottom of bulli pass)
one day i threw 4th back 3rd compression lock + rear wheel aqua plane and only just missed a cement wall from that day i always gave the throttle a kick. i only had my p's for 3 weeks
my style has changed as well as most do i've gone from a sloppy as hell double clutch quick tap as fast i could, to just given it a nice half sec of throttle, nice and smooth
