It is more money to buy the whole ROW 030 setup but the labor is virtually the same as the spring change alone.

Suggestion

For street and occasional track use the H&Rs should be fine, according to H&R they are designed for stock shocks.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

10 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

I'm going to add H&R springs and a GHL exhaust to my 01 C4 Cab. Has anyone else done this mod to their 911? If so, please provide feedback on the results. Thanks!

POST 2Original post

H&R springs where a great mod for my C2....no experience with GHL, I have the PSE.

POST 3 / ORIGINAL POSTEROriginal post

Big6Dad, how did the H&R springs change the ride and handling?

POST 4Original post

H&R springs will give you a slightly stiffer ride and handling is improved but make sure that your stock shocks are not shot when swapping springs. **TIM**

POST 5 / ORIGINAL POSTEROriginal post

the car only has 12k miles on it, they should be ok

POST 6Original post

Bob, my car also had about 12K on my 04 C2 when I made the change. My impression to the change is that the car rode a little better as a daily driver ( read not as harsh ) but still does well at DE events. Hope this helps...

POST 7Original post

Just be sure your shocks don't bottom out on hard cornering, or you will get significant bumpsteer, not fun at high speed. I have GHL's, sound great, if you want to hear 'em pm me. Chris

POST 8Original post

For street and occasional track use the H&Rs should be fine, according to H&R they are designed for stock shocks. That said I would strongly suggest that you read the US vs RoW M030 write up on the PCA site. There are a few potential problems with an unmatched spring and shock combo, things like bump steer as C4S mentioned. You would think though, that H&R has their stuff together being an oem supplier (GT2/3). It is more money to buy the whole ROW 030 setup but the labor is virtually the same as the spring change alone. To each his own but I would hate to find a problem after it is installed. The GHLs sound very good, similar bark to pse, and no/zero/nada drone or resonance. Plus you can't beat the price.

POST 9Original post

Bought my GHL during the winter when they had a special going on, -had them installed last month. At first I did not like the sound, a little "ricer" for me, but as has been mentioned on prev. threads about GHL's is that they do deepen over time and now I like the sound and find myself purposely dropping down a gear to hear them.

POST 10 / ORIGINAL POSTEROriginal post

thanks everyone for the feedback! I'll post my opinions after the install next week!
