It makes a dramatic difference, even if the engine start switch can't be disabled.

could you be a little more specific?
i was thinking of using one, but after I talk to my VW driving co-worker I decided not to. His words were, "why get a manual then"....

i don't even think i understand the point of that statement, with respect to a clutch stop.

i believe a stop would make a difference if you find the clutch "sloppy"... it feels like there's 2 or 3 inches of free play in these clutches.

I totally agree on that one. If pushing in the clutch the extra 2 inches made a difference, then fine, but if it's wasted energy, why bother? Wasting energy doesn't make it more enjoyable...

OK, more specifically, by eliminating an inch or so of clutch travel, shifting is substantially less tiring, I'm quicker, more precise, and a lot less likely to have to rush a shift because I wasted ten minutes in the clutch dead zone.

It's also $20.
Of all the possible mods out there, this is probably just about THE cheapest perfvormance modification. Try it. If you don't like it, you can always throw the clutch stop in the garbage.

my concern is the start button

i read the info on bmw330ci.com about defeating the switch, are there other ways to defeat the switch?
My switch can't be defeated.
There are two types. The plunger type described there and some sort of electronic (magnetic?) type that's integrated into the clutch cylinder.
If you have the plunger, it's any number of ways that result in the plunger getting depressed. If you don't, then you just have to make sure that the switch engages at the lowest point.

If you're sitting in your car with the engine off, but the key in the run position, depress the clutch until you hear a click. The click is the minimum distance that you HAVE to push to start the car. This is probably about an inch away from the stock clutch stop.

buy a clutchstop and improve your driving experience.

i think one thing is very important to clear up: there are two clutchstops available at the retail level:

the UUC big boy which works well in e36s and z3's

AND

ron stygar's clutchstop which is basically an OEM piece on a longer bolt.

Ron's clutchstop works quite well in our 2002 325xiT. it decreases the useless clutch travel by 2-2.5 inches at least.

if you need more information on ron's clutchstop, you can find his webpage, get in touch with him, and order a clutchstop from him. he's very kind, informed, and can make almost anything. a true automotive ninja.

~ $20.

i know those are the two clutchstops out there

are there any specific reasons to choose one over the other? will either clutch stop make it easier or harder to work with the start switch? i know some people here and on the .org used the uuc clutch stop. oh well so i buy and try... either way.. thanks

they should functionally be the same. the premise behind the uuc bigboy is that it provides a broader stopping surface, as the clutch lever does have some lateral movement.

sorry, i would say incorrect here.

the UUC motorwerks clutch stop is so wide, it actually impedes the clutch travel even more than ron stygar's clutchstop.

with the UUC big boy unit, my wife's 325xiT will not start.

since stygar uses the same width rubber screw-cap type stop, it still allows for easy starting of the car.

but in essence, they do the same thing.

not to be argumentative here, but i was correct in saying the BigBoy is broader (larger diameter), and that the clutch lever has lateral play-- that's why a broader surface would be safer.

whether or not the car will still start has to do with the depth or thickness of the stop... not the width. i think we are just labeling the dimensions differently.

regardless, i don't think i said anything that was incorrect.

you, sir, are correct!

i am used to the uucmotorwerks unit because i use it still works when there is side to side play in the clutch pedal (happens!) the stygar unit works less well.

but alas, these newfangled e46 thingies are smarter than us humans, so it's damn picky about what it will let us do in terms of clutchstops.

ron's unit, i suppose, looks nicer because it looks perfectly stock.

it's so simple i'm surprised bmw doesn't allow us to have adjustable clutchstop a priori; but too many lawsuits for that plus premature clutch wear if people set it incorrectly.

anyways, to summarize: clutchstops really help a lot in day to day shifting.

I found that the UUC clutch stop works perfectly. You just have to play with the nuts and washers and find a combination that works. I settled on both nuts and one washer. Any more and my car won't start, either.
The UUC gives fantastic feedback, too. The stock stop is mushy, almost.

nick -

so you dont have any start switch mods? thanks for the info
No, no start switch mods, I have a post march production vehicle, and they changed the method. No one has been able to defeat the new switch.

For my 2002, we had to trim about half an inch off the bolt with a hacksaw to get it to work. Otherwise the car wouldn't start. My understanding is that this is only a problem for 2002's and that UUC is working on a new version (Big Boy 2.0) that works in a 2002 without modifications.

I still recommend it, but make sure you own a hacksaw.
