im running 10/12 stock valving. imo its perfect for me.

 

This is good news. Sounds like a revalve isn't absolutely required.

I am running 255-40-17 BFG R1S tires on 17x9 rims. They are as wide as a 275 hoosier though and considered a cheater tire.

Thanks for the info fellas. Now I need to find some 12k springs.

 

Stroke is shorter, but the spring size is the same.

 

^Oh you're a genius

Jeff- let us know what you decide to go with and please share your findings. For those that replaced their springs, did you go with a particular brand such as Swift, Eibach, Hypercoil? I know lots swear by swift but I question whether they are actually better than the aforementioned brands...

 

I got to thinking last night .... if its only a couple hundred bucks for a revalve then that is what I'm going to do. No sense in taking shortcuts on one of the most important items in the parts list especially if it could shorten the lifespan. I'm attempting to gather quotes for the revalve and will likely get springs directly from Ohlins.

Getting the rears set up for 12k with the possibility of a 14k future sets the entire car up for future spring rate increases. The rear 12k could go to the front and I could add 14k to the rear if desired. I'd rather entire system be dialed in perfectly.

 

i have read a few artickes that say swift and hyperco are both pretty damn good. id guess eibach ERS are just as good. you can get a set of 4 swifts for like 400, i think hyperco might be a tad cheaper. actually looks like PSI sells both hyperco's and eibachs for about 80 bucks each.

im running the old gerard spec ohlins (r/t's i believe). i think they can handle 10k/12k i was told.

 

I'm running 600/700 lb Hyperco's from here http://store01.prostores.com/servlet...ngs:8in+Length "The Shock Shop" Fast shipping, $54 per spring.

 

Im not an engineer nor do I know a lot about the characteristics of springs however so Im merely thinking out loud here but what really makes up a spring? What makes certain springs better than others? The only factors that come into my head are the following:

-Consistency
-Durability
-Weight

Do we know who makes the springs for Ohlins? I know that not all springs are created equal but I am not a professional so I do not demand the absolute best. If I can spend 1/2 as much on springs going with Hypercoils vs. Swifts I can then allocate that savings towards a revalve instead.

 

I am pretty sure that Ohlins uses Eibach springs

^Thanks, that is the excerpt that I read in the past. My question remains though as to how much of that is the truth vs. marketing hype. I dont mean to sound like a skeptic but I would love to see some cold hard facts. There must be some independent tests floating around the web. When I have some time I will see what I can come up with...

 

if you lay a swift next to a hyperco the swift definitely has less coils

 

Like a Titanium spring.....they have way less coils compared to a regular spring. There are always questions about how linear the Titanium springs are.

As long as the spring is linear and durable, what else would matter?

 

Yeah, if this were the case why haven't they linked up with any major suspension manufacturer?

 

spring rate consistency is important too:

ive read a few mentions of them having better "frequency" (which i believe is basically reaction to things like bumps) but never found any hard data on that.
