bodilx6 Posted August 22, 2009 Share Posted August 22, 2009 anyone know what the tolerances are for the j-spec discs? I mean when are they worn? I have only been able to find the measurements for the EU spec..(2.5 cm front and 1.5 back, to my recollection) Quote Link to comment Share on other sites More sharing options...

bodilx6 Posted August 24, 2009 Author Share Posted August 24, 2009 uh-uuh... Think my fronts are below 30mm (will double check) and my rears are 16mm. Chris, do you recommend stock Toyota discs or would you suggest another brand? As you know, I just got your fast road car pads on there and I use the car for normal road driving except for the odd trip to the ring once or twice a year. Should I start saving for a big brake kit (probably not) or just stick with what I've got (maybe some other discs or?) Thanks /Stefan Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted August 24, 2009 Share Posted August 24, 2009 I use either stock or exact copies, TUV approved. I have found all the fancy E-Bay ones (drilled, lots of grooves, fancy coatings blah blah, to be junk. The only worthwhile upgrades are a bigger set up altogether (UK discs and calipers all round, then UK with my floating AP disc kit on the front, like Wes has, and then the big Brembo kit all round. If that's STILL not enough you can get into custom stuff with dual master cylinders and remote bias adjustment, but you are into BIG money! I would fit a set of my race pads all round for the `Ring, and use my fast road ones the rest of the time. For a single track day a big brake set up is probably a needless extravagance.
