Hello All!
I've been hanging around for a while reading up and getting to recognize all the regulars here. Figured it's about time to get a post out.
After parting ways with my '02 WRX, I've decided to jump into a build for the S13 coupe I've had sitting for ~5 years that I acquired on a whim years back.
The goal for the car (for now) is to set it up mainly as an autocross car that will see a couple track days a year (we've got an autocross community but not many road courses in MT). I have been to a couple events and seen the likes of logr tearing it up, that car is really what convinced me to start this project. I also plan to drive the car a couple times a week on the sweet two lane highways that abound in this big sky country but it will not be a DD by any means. This year is suspension/braking, next year will be engine if I decide to take on part two. I've got a full Z32 Al brake conversion (would have loved to go Def's Wilwood route but that's $$$ that I budgeted elsewhere) and part of my 86XX/GC setup amassed in my garage. Just got the custom housings, so many thanks go to Richard for the excellent craftsmanship and really good service.
I've now reached my first hurdle: spring rate/length. I know I won't get this perfect the first time and it will take some tweaking, but I want to at least get in the ballpark the first time. I'm not into slamming the car, just lowering it to that CG/roll center balance point. RC correction will come later, probably by Def's budget FLCA method. Tires are 225/50/16 (skinny, I know, but it doesn't take much to put down 130rwhp worth of KA24E plus I had two sets left over from the WRX). After much scouring on here I was sure I was gonna go with 500/400 lb/in 6/7" f/r but have recently come across people saying go stiffer go stiffer...so now I'm thinking more like 550/450. Also many people seem to be running 7" f & r. I'd love some info on peoples' set ups and any input you're willing to give. While you're at it I'd appreciate input on the 8610/11 split vs 8611 all around...worth it? Thanks for any and all input in advance.
I wanted to close my first post by saying thank you to a forum of seemingly awesome people who are willing to help out others, are not into flaming, and who know what it really means to go fast. I was on an FSAE team for years, and while that is a whole other story and a sh*t show of it's own kind, I truly appreciate the intellectual level of this forum compared to others that shall not be named!
