Springs

[racer240sx]

I have a 93 240sx I am building and was wandering what spring rates I should start with? I plan on running at Atl. Nash, BIR, Sebring, VIR. and maybe a few other tracks. I have ran BP. & GT1 corvettes till now so these cars are new to me. I have Whiteline sway bars. I have 205/50/15 R6's but plan to run 225's when I get thru with testing. What starting camber angles and toe settings for baseline. Any help would be great.

I ran 400 front/275 rear. Pretty soft, so you let that rear suspension do it's thing. I know some guys are running a lot stiffer these days. Your camber won't be determined until you work out your spring rates and see what temps you are running across the tire. Having said that, I was running in the general area of 3.4 front 3.2 rear. I would run zero toe in the rear. The front toe all depends on what you like as a driver. I little toe makes the car very predictable, toe out, twitchy.

Take a look at all the parts I have for sale if you are building up a car. There is some good stuff there. The shock package especially, and the motor is top-notch.

Buy Tristan's set up and go drive.
I would pick them up if I did not already have the same setup.
Let us know if you need anything else.
I have a stack of 240s and have been running mine for around three years now.

It also depends on your shock package. Tristan has the Advance Designs for sale that are very good. In my S14 I ran 450 fr / 375 Rr but had custom front Nascar "blade style" bar built. I ran NO rear bar. In our testing I found that most "off the shelf" bars were miserable, especially the rear. I tried every off the shelf unit available and threw them all in the trash. Camber was similar to Tristan at -3.5 front and -2.75 rear. I prefereed 1'32 toe in at rear and 1'32 toe out front. Usually was about 3 deg caster front if i remember. Good luck. Man I miss this stuff...Chris

My setup is very similar to the guys above; 450f/325r springs with Koni sports all around, GC coilovers & front camber plates, Whiteline front/OEM rear sway bars. I run a little less camber; about -3 front and -2.25 rear, and 0 toe at both ends. You should also consider upgrading the rear suspension bushings to spherical bearings, and replacing the subframe bushings with solid bushings. SPL Parts sells most of the pieces to do these, and there are one or two other places that will make them up for you.

I like to be a little stiff in the front, and a little soft in the rear. Does any body run a front splitter. I have seen some small spoilers, but them seem to be more for looks. Some of the tracks it should help with cooling as well as some down force. What are your thoughts.
thank you for any advice.
