Just another spring rate thread.

[djjerme]

lots of sizes and rates, seem to come out just like they went in, just dirtier.

Which is what I like about them.

Agree!

I should have them by the end of next week. If that's the case, I'll try and install everything over the weekend.
Harshness doesn't bother me a bit. Tennessee roads are pretty nice and my daily commute to work and back isn't that far.

I am very interested in what you think of the new setup. I have basically the same setup as your current setup and was considering the same setup you just picked up. My car is a dd/autocross and I am worried that the GC would be to harsh for everyday. I would love to get your feed back on the new setup.

Yeah I highly recommend hypercoil springs if you need to change your rates. Had them on my autox truck. Great stuff

[djjerme]

Heck, check in with the circle track or dirt track guys, they seem to always have shelves full of different spring rates and lengths..

I went ahead and pulled the trigger on the original recommended GC setup. The guy I spoke with today was different and he thought the setup was a little "extreme."

Which is precisely why I wanted input from other e30 owners. I could recommend spring rates for a Honda but unless I drive one i can't say how it'll react.

Hopefully it isn't too tail happy.
At least springs are relatively inexpensive.

See, I set my car up with a ton of oversteer. Currently have 650f/750r. But I am reconnecting the rear sway before the Rat Race, and swapping the GC setup off my other white car, since my home built coilover setup blew up on one corner..

GC didn't get their reputation by just pulling spring rates randomly out of their arse and not knowing anything about car setup.

Jeremy, I generally would agree with this. But given what all of us run for f/r rates,
I just don't see how GC's soft front/stiff rear recommendations would work.

At Portland, I find that 600f/700r is too prone to oversteer for me. And I came out of a 2002...

I'm planning on going with a GC setup going with 450/650 setup with a big front sway and little to no rear sway in the back. Seems to be a autox proven setup

:up: thank you for the advice

Just go with what GC suggests.

The fact that you are just going off random threads and sh*t you read on the interwebz just re-enforces this even more.

GC didn't get their reputation by just pulling spring rates randomly out of their arse and not knowing anything about car setup. As long as you gave them all the information they asked for on your setup, they'll give you a decent recommendation. Call them up and talk to them.

Then once you get used to the setup start tweaking settings. The nice thing is springs are cheap if you decide to monkey with rates..

Go with the advise of someone who's company name/reputation/financial future is dependent on the advice they give, rather than some random dude who has nothing invested in your satisfaction with the suspension setup.


Then ask us what to change once you have played with the setup on your car for a season.


*to add, I have played around with several different rates/bars..etc on my own race car. Even ran without rear sway (it's currently set up that way after I snapped a swaybar arm in half - long story..)

That being said - if you are not going full 'tard with the car, I would not suggest any of the setups I have ran for coilovers, the car will not be fun to drive outside the track. And I drive my car to and from the track.. It's a PITA to drive a full race setup suspension on the street - you will feel EVERYTHING in the road, and even somethings that aren't there!

I talked with GC and they recommended 550 front and 850 rear but I have read where many people have issues with oversteer. I saw a thread where one gentleman was running 550/630 with a 25mm front sway bar and no rear sway bar and he loved it. Has several SCCA wins with that setup. Then I have read that e30s love 150% difference in springs which is what GC recommended...so.....?

Do you have M3 style sway bar links up front?

No. Sway bar is control arm mounted.

I believe you're going to want less rear sway bar with the recommended setup from GC.
The new suggested rates have more rear oversteer bias that H&R race's rates mathematically.

Then again, you are switching to Koni's at that point.. so another variable has been added.

I'm not against ditching the rear sway bar and increasing the front if needed. Supposedly, the bilstein won't work with springs much over factory rates and re valving cosys as much as buying the single adjustable koni.
