Clutch Helper Spring help!

imsimplee · 04-18-2015, 09:13 PM

Hey guys, Looking to do the clutch helper spring mod but cant seem to find the spring anywhere...I tried the century spring site but it wouldn't sell anything under $40.... So if you could help me out with a link for "Century Spring Corp. P/N 72577" It'd be greatly appreciated!

LMBMike use to sell them. check if he still does.

Also check G37 forums. I bought one locally from a G37C guy a while back.

Have you taken stock spring out already? If not, it is perfect without any spring.

I agree. I took the spring off and it's perfect that way.

Does your pedal return to zero position without the helper spring?

mine did not. so just bought the century spring.

I just installed mine this weekend after having it for 2 years

. Still haven't gotten to drive it yet after the install. But if you can't get one from LMBMike which is where I got mine so long ago. You can pick one up here on eBay.

I have one available now - $20 shipped and paypal-ed to lower 48 for anyone interested - just PM me.

I've installed the RJM clutch pedal - it allows you to adjust the clutch engagement point and the 'window' of engagement more precisely: rjm clutch pedal

However, the century spring is a very cost effective alternative and does improve the feel of the clutch engagement but doesn't have the adjust-ability features of the RJM clutch pedal.
