OEM replacement is made by sachs im pretty sure.. No need to upgrade really. Maybe a lightweight flywheel if youre feeling especially daring, but thats about as far as trans upgrades go

What deficiency of the stock clutch are you hoping to correct?

Nothing really I can feel my current stock clutch getting ready to kick then bucket and usually when I replace something I upgrade.

jb racing should have the complete set, also clutch master has some clutch avaliable.

i think pre-lci model uses 32 lb flywheel compare lci 22lb, so u should be able feel big difference with those two replaced with single mass unit.

Mine's going to be on the way out in a year or less likely. Going to try to replace with a "racing" clutch too. While I don't know if it will do the same on the bimmer with a (hydraulic?) clutch, I know I loved the difference that a King Cobra stage 2+ clutch made on a 98 mustang GT. Firmed the pedal up to the point it was almost a legpress. I love that feeling.

If an upgraded clutch won't firm up the pedal, is there any parts on the market that can do so?

not 100% sure on this, but you have a BMW. its not going to have a clutch like a mustang, trans AM, etc, american muscle car.

BMW is going to be smooth, and a new clutch will most likely not give that really heavy pedal feel, travel, etc like it did on your 98.

My old camaro was the same thing. Spec 3 + and it was alright til you got into traffic, than it really was a b!tch.

I do have a BMW. I Don't expect it to be like the GT, I just wanted to know if there was any way to firm up the pedal. I know its going to be smoother and not like a muscle car, but I just don't like how it's so extremely feather light. Is there any mods to give it a little resistance, if not a clutch, a hydraulic valve or something?

Excuse anything that might sound stupid. Still new to modern things like hydraulic clutches and the such and don't exactly know how they work (differ from a mechanical clutch) or what you can do to them

A heavier pressure plate will do the job. One that holds 450 ft/lb tq is going to give a heavier pedal than one that holds 300 ft/lb.

The hydraulic system creates the mechanical advantage instead of the leverage on the wire. Not too different from how hydraulic braking systems work. Like said before a different pressure plate will make it heavier but idk why you would want to do that. Its just gonna suck in traffic. Maybe just get rid of the CDV and get a clutch stop for a bit of a better feel.

I went with a clutchmasters stage 2+ with a new stock dual mass flywheel and it made a huge difference, it firmed up the pedal big time and engages so quick now. No need to upgrade the flywheel unless racing alot, just do a stock replacement.

Also if you have an aftermarket clutch stop on your car you will want to revert it back to stock bc the clutch engages so much faster now it needs that extra space to allow the clutch to fully disengage when shifting. Otherwise you will have trouble getting it into gear at high rpms
