Thread: Springs for Koni's w/ GC Coilovers B13 ...a little help, please.

I am in the process of putting together GC coilovers with CSK. (Spec-V's all the way around.)

I picked up B13 GC coilover kit on Ebay. The springs are both 7'' with spring rates of 200 & 300.

My options are: 1. try them like they are, even though I think the rate is a little low, and I think the 7'' spring is too short for the front.

2. Keep the spring rates as they are, and buy a 10x300 for the front.

3. Run the 7x300 on the rear, and buy I dunno...8x350 on the front.

I've been reading suspension threads until my head is spinning. Originally, I was planning on doing 350lbs w/ 8 inch spring in front, and 300 w/ 7 inch in the rear. Then I saw the setup on Ebay & I saved $130!!! Which is almost exactly the price of the two springs that I am going to probably end up buying.

This is my daily driver, and I don't want it to be too horribly uncomfortable. I say that I want to try to autocross or take it to the track, but I have owned it for three years, and I have done neither. I just want my car to have a firm ride that doesn't bottom out when entering a driveway. Oh, and it should handle like a racecar. Think M3, that's what you should be benchmarking.

What do you think?

Thanks a lot!!!

Youll be fine on the 7in spring

Thanks for the reply. I guess my original post was kinda long. What I really wanted to ask was:

Best spring length/rate for b13 sentra w/ koni spec v and GC coil over.

Thanks

If it was my daily driver, I would keep it stock.

Best spring rate is the highest one you can withstand.

This,


and this



do not go together. FWIW all the racecars run really high rates. Mine is at 500/600 and it's too soft!

I was kind of being a smartass when I said "racecar.' I know there is a tradeoff with spring rate and comfort.

I should've said handle like a high performance European sedan. If you've ever driven an E46 M3, that's what I'm talking about.
Handles great + reasonable ride

Right now (stock w/ worn out shocks & disintegrated bushings)...The ride is bad and it handles like crap.

I tell everyone that I want my car to be a racecar, but I'm mostly kidding. A real racecar would be a horrible daily driver.

BTW I'm going with 350/300.

Thanks for the help!

Oops, I was typing too fast...I meant E36, although E46 would probably be about the same.
