Tommyd16 Posted April 26, 2015 Share Posted April 26, 2015 Is it ls400 brakes from a v8 that are the same as UK supra brakes? Link to comment Share on other sites More sharing options...
j_jza80 Posted April 26, 2015 Share Posted April 26, 2015 No. The calipers are a similar size to the UK's, but are aluminium so they are significantly lighter. The pistons are the same size as the UK spec calipers. The LS400 discs are smaller than the UK's, aren't directionally vented as per the UK's, and are heavier. The weight increase of the disk mitigates any weight saving on the calipers (as the discs are rotating mass) In summary they are a decent, cost effective upgrade over the J-specs, but aren't in the same league as UK's. The main issue with the LS400 upgrade is that it will increase the front brake bias when using j-spec rear brakes, and the UK rears aren't suitable with LS400 fronts IMO.

Tommyd16 Posted April 26, 2015 Author Share Posted April 26, 2015 I have UK fronts. I was going to go for ls400 rears. Will they fit? Link to comment Share on other sites More sharing options...
j_jza80 Posted April 26, 2015 Share Posted April 26, 2015 No, bolt pattern is totally different. If you have UK front's, just buy UK rears. Link to comment Share on other sites More sharing options...
Tommyd16 Posted April 26, 2015 Author Share Posted April 26, 2015 That's a shame. Can get ls400 rears for £90 from a breaker Link to comment Share on other sites More sharing options...
