Can anyone out there give feedback on pros and cons of full spring removal versus replacement with the MTec spring?

kbye started a thread on 4-17-15. Go to Search and type in mtec clutch spring and scroll down until you see it. I don't know how to link too well. it has what you're looking for. good luck!

It's so much easier to find the catch point without "bouncing" a shift.

Like someone said above, I felt like a n00b driving this car. and this was after 4 years in a BMW E90, which has the notorious CDV (clutch delay valve) that also makes you feel like you don't know how to drive stick properly.

I don't understand the need for OEM's to put this crap in. If you're buying a stick shift and you don't know how to drive it properly, DON'T BUY ONE!! No need to water the cars down for those of us who do, "just in case".

Thanks! I found the thread, and I think I'm going to go for the MTec spring. I really struggled when I first drove the car, having come from other manuals with heavier clutches, but I've got used to it fairly quickly. Would still like more resistance/feel though, so I'll give MTec a try.

I know exactly how you feel about that clutch and I have the Mtec spring but have not installed it yet. I did however change over to the 3/4" diameter slave cylinder recommended by Ultramaroon in his long thread and it is a different car now. BTW, I still have the OEM spring in place and have not tried driving without it as I want the pedal to come all the way back up.

Popped the spring out over the weekend. I don't know why I waited so long to take it out. Pedal movement isn't as easy as it used to be, "like a real clutch should be" and engagement is much more predictable, highly recommended and fully reversible 👍 thanks OP!

Have yet to do the spring removal but now I'm wondering just which one is the mod that nets a better feeling clutch...? Difficult to answer, I bet.

There is a second part to this mod that really make the stock clutch feel perfect for virtually everyone: clutch pedal height adjustment.


I have "clutch modded" +30 cars so far, and have gotten nothing but rave reviews. Remove the helper spring, then lower the pedal to be about even with the brake pedal. The goal here is to get rid of most of the extra travel the pedal has near the floor. This lets you use the clutch while keeping your heel on the floor and is an absolute MUST for all MT owners. The guide for doing this can be found here:

I've been driving on this setup for 30k miles and have had no issues with clutch chatter, unusual signs of wear, or any other problems. I've owned/driven a lot of manual cars over the years, and since doing this mod, this is one of the best clutches I've ever had the pleasure of using. Reducing the height also will extend the life of your clutch pretty significantly.


It's free and it's reversible. Stop reading this, go out to your garage, and do it right now. 15 minutes at most. You'll be glad you did :)


EDIT: For those curious about this spring, it has been in all WRX/STI clutch pedals since mid-2000s. Subaru just kept the same design for the BRZ. Problem is, the WRX/STI have VERY heavy clutches, so helper springs are pretty much a must. The BRZ's clutch is comparatively very light, and so the helper spring is really unnecessary. Seriously, why are you still reading this? Go fix your clutch!

Can someone with RHD model and removed the clutch spring please provide some guidance on how to do it?

Wont it be the same, just other way around....

I think it was covered in the other thread. If memory serves, this is very hard to do on RHD models since there is a large metal plate blocking access to the spring in that configuration.

This morning I drove my 2004 Mini Cooper S for the first time since picking up the BRZ a couple of weeks ago. I couldn't believe how heavy the clutch felt in comparison! And when it was my daily driver, I was totally used to it. Just goes to show how easily we adjust between different clutches.

I think somewhere between the two would be ideal, so the MTec spring is likely the way to go for me.

I've been looking for this! Thank you sir.

I removed the spring today and I can't tell you what a difference it made. I've been driving a manual for 20 years and when I got my BRZ I had a hard time engaging the clutch at the right time. I was either slipping it or letting in too hard. With the spring removed I can feel exactly where the clutch engages. It makes it easier to pull out from a stop and to shift smoothly.


I can't comment on other springs but to say that it would probably make the clutch press easier while giving less feel. I would recommend just removing your factory spring first and then if the clutch is too stiff, adding an aftermarket spring. The more spring tension you use, the less clutch feel you are going to have. I prefer it with no spring at all.
