Did a search here and on the net but couldn't find an answer to this question. If an an owner can confirm that would be great. Do the RS coilovers have seperate adjustment for spring preload and shock body length? Or is the spring perch the only means of adjusting ride height? Thanks.

 

Okay, Jim (GSedan35) answered my question. The answer is no. The RS coilovers DO NOT have an adjustment for shock body length. Pretty expensive setup IMO to not have that feature. But then again, when was HK$ ever inexpensive.

 

^ yes, i totally agree. also agree with HKS being expensive period! the new Cusco's (in cabin dampening feature like Tein EDFC), SR's, and the over rated Tein still are great buys IMO in terms of fully adjustable coil over's.

 

What is the advantage to having these features? Thanks

 

The main benefit to having seperate adjustment of shock body length and spring preload is to maintain the full range or proper amount of suspension travel. Another benefit is to be able to fine tune the amount of spring preload for optimal performance. Lowering springs with shocks and coilovers with only adjustment at the spring perch do not maintain suspension travel. So the lower you go on those, the earlier your shocks can bottom out.

 

How low must one go on the RS before not having these features is a liability? Is this a concern if a minimal drop is dialed in? Thanks.

 

^ it's not a concern if you lower them to the given recommended specs. however, you will (9/10 times) bottom out in a matter of time if you lower them more than the recommended specs. i believe these aren't available for overhaul either.

 

So if I use the RS to lower my sedan at most 1.5" should I encounter any problems with bottoming out? If the RS is not available for overhaul, how long should a set last? Because I agree with you, they are not cheap. Thanks.

 

1.5" should be just fine. I wouldn't worry about it. The listed range is 0-3 inches drop. I'm not 100% sure, but I believe the RS coilovers were made specifically for the 350Z and G35 coupe, which we know are lower to begin with stock compared to the sedan. So the 0" drop setting for a 350Z may already mean a small drop for a G35 Sedan.

 

Thanks dklau33.

 

No problem.
