Hey guys, ive driven FWD honda's for the last 8 years of my life, owned a 2000lbs civic with 500lbs springs in the front and 300lbs springs in the back, and a prelude with TEIN HA's with 12kfront and 10krear(forget what the conversion is to LBS, i think 800lbs front and 600lbs back?) in the back. Both of these 2 rides of mine were stiff, and a tad bouncy but i can take it due to how much fun and well they took corners and back road runs!


My question is, i want to do the same with my G35 and plan to get some nice suspension for it. Which would you reccomend? As i am looking for fairly agressive spring rates, but not FULL race car agressive spring rates.

And on pillow ball mounts with my old civic, i dont know if it was because i was really dropped or that the stock ones are plastic, but when i would hit a pretty hard bump i'd hear a loud bang! That was annoying when driving in the city, will this happen with aftermarket pillowball mounted suspensions in g35s? Am i better off using stock pillow ball mounts?


And last but not least, what good suspension setups do you guys reccomend? Flex? I remember with flex for civics and preludes, they werent agressive enough for me, Tein HA's were more agressive than these.. and doubt this type was even ever made for G35s as they are discontinued now.

But shoot away friends! I'd really appreciate it, as all i know is theres a difference between spring rates for cars looking to kick the back out(drift) and those who want to go in auto-x or circuit racing!

 

i would start by reading all the stickies at the top of this section to familiarize yourself with the suspensions available, and their specs, narrow it down to a handful and then ask some specific questions

 

+1, those stickies would answer all ur questions that u posted here. Its a long read but worth it.

 

Wow. Just looked at the sticky with all the coilover/suspension quotes/ comments thread.

INCREDIBLE!


But with that said, i noticed a pattern with alot of coilovers, same front and back Spring rates? And then some would have like a 5xx front and 3xx rear. Why the difference? What does this make in track driving? Or is it something with daily driving?

Whats the weight distribution on g35s? Anyone know?


Just wondering guys, just dont want the back kicking out on me! LOL Im kinda scared as this would be my first RWD ride. LOL Just used to snow plowing with my FWD if it got bad!


Thanks again ! Great sticky!

Edit: Redlude, were you ever on Prelludeonline.com?

O and also back to this question, could anyone answer this with their personal 2 cents?


And what are the typical RWD spring rates you use when trying to go more for auto-xing compared to drifting? Or Vice versa?

 

Different companies decided to release various springrate setups with varying biases, some of which were actually tested, and some that may have been for other reasons. Some of this may be balanced by stiffer valving biases which are more difficult to quantify. What I can say is that the OEM springrates are stiffer in the rear and there is likely a reason the nissan engineers designed it in such a way so I would personally look for a setup with a rear bias or near neutral bias if possible. The G35 already understeers from the factory quite a bit so it will feel somewhat similar to a prelude, the best way to adjust this to your liking is with a good set of adjustable swaybars combined with some coilovers or springs

BTW, yes, I was on PO.com before I joined driver. I'm pretty sure I remember you being a member also, did you have a green 5gen? Maybe it was another car. Alot of us have moved on to g35's. You'll see them around if you browse

 

Hehe. Good to hear, yea i am looking at possibly getting the TEIN Flex's now that i look at their spring rate and see the comments in that sticky.







This was my old girl. back in 02'.

Good to hear about other members moving on, my black stallion will be relived through my next G35.

And before this i had a K20R hatchback, which i just recently sold to get a black G'.

Hehe.



But thanks for the feedback, anyone else on comments about suspensions with Pillowball mounts? Is it making that knocking sound when hitting bumps or onramps??

 

It appears that few bother to calculate the actual as installed spring rates as they apply to tire road interface [all that counts]!

Springs that are mounted with any angle ACT as less stiff [pounds per inch of body roll].
Springs offset inward from hub ACT as less stiff at the tire.

The TRUE AS INSTALLED STIFFNESS is the only thing important.

for example a spring bottom attached midway in a lower arm will ACT as if it was 1/4 as stiff as published brcause a 1' rise in wheel will only compress the spring 1/4"

Same with a spring mount at a 45 degree angle where spring will only ACT as 50% as stiff as published.

Springs are selected to hold up body to desired road clearance and to allow +- 3" [midpoint] of shock range.

Springs are selected first to match fore/aft weight ratio then front is made stiffer by 5-10-15% than above to induce understeer for average driver.
Same with oem sway bars or a balance of two. Front made way too stiff to induce progressive understeer increases as turning G rise!
