98-00 Lexus LS400 Brake Caliper Conversion on 92-00 Lexus SC300/SC400

October 2, 2015

One of the most sought after modifications in the SC community is swapping the stock brake calipers for either the 98-00 Lexus LS400 front brake calipers or any MKIV Twin Turbo Toyota Supra front and rear brake calipers. There are a number of reasons why it would be a good idea to do either. Both options are made of cast aluminum, which means both are much lighter and is a natural heat sink, and does not heat up as much as the OEM, which is made of cast iron. Both designs are also fixed calipers, more commonly used for performance and reliability while the OEM are a floating or sliding type. Both also have a total of four pistons on each side for the front brake calipers, and utilize a bigger brake disk, which translates to more surface friction, which means more braking power. The only difference with either is the price. Since the Toyota Supra’s book value is way up there, a used set of the front brake calipers alone can cost anywhere from $500-700+, brand new can be bought for $1500+ from the dealership, and the rear set goes for $300+. While the LS400 brake calipers go for $200+ used, if you’re lucky enough like I was, I found mine for roughly a $150 from a local junkyard.
