Clutch Masters 11 BMW 335i/335is E90 Turbo FX100 Sprung Rigid Clutch Kit
If your N55 335i has started to flare in the upper gears after a tune, or the original clutch is simply worn out and you want more holding power without turning the car into a race car, this is the Clutch Masters kit built around part number 03075-HD0F-R. It is aimed at BMW E9x and F-chassis cars that keep the factory dual-mass flywheel, and it arrives with the pressure plate, disc, release bearing and alignment tool in one box.
Our listing title calls this an FX100, but Clutch Masters catalogs part number 03075-HD0F-R as its FX250 stage, and the part number is what ships. The 0F code means the hybrid disc: Fiber Tough friction material on the pressure plate side and steel-backed organic material on the flywheel side, sitting on a marcel spring wafer. The -R suffix means a rigid disc hub, which Clutch Masters specifies for use with the OEM flywheel. Paired with the Power Plus I heavy-duty pressure plate, the maker rates it at about 110 percent more holding capacity than stock.
The pressure plate clamps the disc against the flywheel so engine torque reaches the six-speed manual. On a turbo N55 the factory clutch is sized for stock boost. Once a flash tune or downpipe raises torque, the stock clamp load runs out first in third gear and above, where the driveline load is highest. A stronger plate and a grippier disc restore that margin. Because the factory dual-mass flywheel already absorbs torsional vibration, a rigid hub is the right match for it; a sprung or dampened hub is what you use when going to a single-mass flywheel.
A slipping clutch does not set a trouble code. Do a controlled check: in fourth gear at about 2,500 rpm, go to full throttle and watch the tachometer. If revs jump while speed does not, the clutch is slipping. Then rule out the hydraulics, because a sticking slave cylinder can hold the clutch partly released. Our transmission slipping diagnosis guide walks through separating clutch slip from other driveline faults, and the clutch slipping causes and fixes page covers oil contamination and hydraulic issues.
The listing is for the 2011 335i and 335is E90. The Clutch Masters application chart for 03075-HD0F-R lists the 335 3.0L N55 (shown as 2009-2012), the 2012-2015 F30 335 N55, 2011-2013 135 N55, 2011-2012 1M N54, 2014-2016 435 and M235, the 2011-2016 535 F10, and some 5 and 6 Series V8 cars. The 335is is not named on that chart, and it uses the N54 engine, so 335is owners should send us the VIN before ordering. Every buyer should confirm the car is a manual with the factory flywheel still in place. More options for this chassis are in the rebuild and clutch kit collection.
If you are switching to a single-mass flywheel or need more grip, compare the FX400 dampened ceramic kit before you buy.

Part number 03075-HD0F-R is listed by Clutch Masters as the FX250 stage, with a Fiber Tough and organic hybrid disc and a rigid hub. The part number is what you receive; the FX100 wording in our title does not match the manufacturer catalog.
Clutch Masters lists this rigid disc for use with the OEM flywheel. A single-mass flywheel removes the damping a rigid hub relies on, so for that setup choose a dampened (-D) disc instead.
The manufacturer chart names the N55 335 and the N54 1M but not the 335is. Send us the VIN and we will confirm before it ships.
Check the dual-mass flywheel, the pilot bearing if your car uses one, and the slave cylinder. Replacing a leaking or sticky slave while the transmission is out avoids a second teardown.
Clutch Masters asks for at least 500 miles of normal stop-and-go driving with no full-throttle shifts or hard launches so the disc and plate seat evenly.
