UKGT500 Posted January 22, 2014 Report Share Posted January 22, 2014 I am thinking of doing this: upgrading the stock 11.8" discs to 13.8 or 14". I guess it's pretty well known that the GT500s just have the same rear brakes as the GT with the possible exception of an upgraded pad material, whatever difference that may make. Anyway there seem to be quite a few options for not a huge amount of money. One that appeals is Vorshlagg's which uses stock calipers on a 13.8" disc. The kit is pretty cheap really but when I emailed them they did recommend using 2011+ calipers that cost about $350 extra even though they are unable to verify what the difference is between the pre-2011 calipers or whether the earliercalipers will fit. This one: http://www.vorshlag.com/product_info.php?cPath=141_142_280&products_id=606 Or there's this from Shelby themselves: http://www.shelbystore.com/product-p/z-2262019.htm Only problem with the Shelby one is the discs won't match my fronts unless I also buy drilled front discs. I was planning on just upgrading the rears. The stopping power is pretty good actually but I am always looking for little improvements to my GT500. Anyone notice any difference from upgrading the rears? Are they likely to lock up or is there a brake proportioning valve that can be adjusted? I have to say my car stops pretty even and with not too much dive.... Thanks Quote Link to comment Share on other sites More sharing options...
