I thought that when doing a break upgrade,like the z32 calipers on an 240sx, that the rear brakes did not need to be upgraded since most of the braking force is in the front. Alsot most big brake kits are only for the front brakes. I found this very informative and technical artical about brake upgrades and the importants of keeping the braking distribution close to stock as possible for high speed braking <

I have the 26mm z32 calipers on my s14 and notice that they lock up very easily. There have been times where I needed to brake quickly and my tires would lock up and I will just skid for a little while almost as if I were hydoplaning, but it does not feel like it is stopping any sooner. Besides the long screeching stops, they don't fade even whith the crappy pads that came with the calipers.
I think the cause of my car sliding so long before stopping is because my rear brakes are not being used as much so the net brakinf force of both the front and rear brakes together is actually less like the article talks about. I was thinking about puting upgraded pad in the rear to help balance this out.
Does anyone have any suggestion, comments, or similar experiences?
