This matters because trims that share a chassis name can differ mechanically: a pure M or performance variant often carries different front knuckles\/uprights, hub geometry, and wheel axial (ET) clearance than the standard models in the same family, so a bracket and hat offset that bolt onto one are not the same parts that fit the other. StopFlex supplies the calipers, pads, rotor hats, floating hardware, and brake lines as a matched system built to your confirmed trim.

There are two rear paths. The first is a dual-caliper rear: a main performance caliper handles braking while a dedicated EPB actuator caliper is retained alongside it, so the electronic parking brake, auto-hold, and hill-start assist all keep working; on this path the rear performance caliper can be the TTSPORT EP4 \/ EP4S 4-piston caliper. The second is an EPB-integrated caliper, a single rear caliper with the electromechanical parking-brake motor built in for a cleaner install with fewer parts behind the wheel; on this path the rear is the TTSPORT EP4 \/ EP4S 4-piston caliper with integrated EPB. Which path fits best depends on your exact trim and EPB configuration, your budget, your appearance preference, and your wheel size and spoke clearance. Confirm your car's rear-brake configuration with StopFlex before ordering so the correct EPB-compatible rear option is built for your kit.\u003c\/p\u003e\n\u003cdiv class=\"scroll\"\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth class=\"accent\"\u003eRear option\u003c\/th\u003e\n\u003cth\u003eWhat it is\u003c\/th\u003e\n\u003cth\u003eRear caliper\u003c\/th\u003e\n\u003cth\u003eBest when\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDual caliper (EPB retained)\u003c\/td\u003e\n\u003ctd\u003ePerformance caliper plus a dedicated EPB actuator caliper, both fitted on the rear, so the factory electronic parking brake keeps working.\u003c\/td\u003e\n\u003ctd\u003eTTSPORT EP4 \/ EP4S 4-Piston Caliper\u003c\/td\u003e\n\u003ctd\u003eYou want guaranteed factory EPB, auto-hold, and hill-start behavior preserved.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEPB-integrated caliper\u003c\/td\u003e\n\u003ctd\u003eA single rear caliper with the electromechanical parking-brake motor built in, for a cleaner install with fewer parts behind the wheel.\u003c\/td\u003e\n\u003ctd\u003eTTSPORT EP4 \/ EP4S 4-Piston Caliper with integrated EPB\u003c\/td\u003e\n\u003ctd\u003eYou want a cleaner single-caliper rear with full EPB function.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003c\/div\u003e\u003c\/section\u003e\u003csection class=\"box\"\u003e\u003ch2\u003eFAQ\u003c\/h2\u003e\n\u003cdiv class=\"faq\"\u003e\n\u003cdetails\u003e\u003csummary\u003eWill this kit fit my exact CLS350, CLS450, or CLS53?\u003c\/summary\u003e\u003cdiv class=\"a\"\u003e\u003cp\u003eFitment is confirmed per vehicle before production.
