There's no point upgrading the turbo without fitting bigger stoppers Picked up rebuilt Celica ST162 calipers from Russ (legend) which have a larger piston and pad diameter not to mention alot thicker disc for better heat dissipation New drilled and grooved discs on the way at the minute to finish off the new conversion..and a comparison against the stock brakes (pictures dont do it justice theyre a brave bit bigger!)
