project:BDR 2003 WRX: STX autox build thread (sponsored by Andrewtech) - NASIOC
Hi, my name is John and I'm pretty addicted to autocross.
This is my story / log / build thread. Take it for what it's worth - not much I am by no means a suspension expert. I will explain my choices to the best of my ability/knowledge, but I'm just one guy who has read a couple of books and a bunch of forum posts. I am getting better at making my car do what I want it to do but I may not always be able to explain why it does what it does In other words, my generalizations should not be accepted blindly as absolute truth. Suspension tuning is freakin' hard, and I can only put so many caveats in here!
Here is a great quote from Lee Grimes at Koni that applies to this thread, but also applies to most everything:Originally Posted by CRX Lee
In late 2003 some friends and I decided to form a motorsports team, project:BDR (project: BDR). Nowadays, it's more like a drinking team with an autocross problem It's not a big formal thing, just a group of friends who all like autocross. So, obligatory shoutout - couldn't ask for a better group of friends.
I would also like to take a quick second to thank the companies that have sponsored and supported my efforts:
-Andrewtech Automotive: Ever since Andrew was a Subaru tech at Hillmuth he has had a reputation for being an excellent mechanic and an amazingly nice guy. When Andrew left Hillmuth in 2005 to start its own shop it was great news for the entire Subaru community. Every time I've needed something, even last minute, they have gotten me back on the road so that I could compete. And they care. And if they screw up, they admit it and fix it. They have the best Subaru techs of any shops in the area, IMHO and their work shows it. Plus, Jake and Dan are out autocrossing their WRX-swapped Street Mod car at a ton of events every year. It's not just a job for them. Other than fixing anything that goes wrong, they also do all my alignments/cornerbalancing - and as you know, that can happen a lot in a given year. They have always nailed my specs perfectly. I couldn't ask for anything more.
-Discount Tire Direct: They have, IMHO, the most comprehensive set of ST* wheels and tires of any company out there: the AD07's, the Direzzas and the Falkens, plus the Enkeis (including the RPF1) and the 5Zigen FN01R-C's. They price match and they have free shipping. For more information, click here.
-Hyperco: Suspension tuning is a big deal and that often means swapping spring rates. The three companies most people think of are Eibach, Hyperco and Swift. In late 2007, Hyperco announced a new line of springs - the Optimum Body Diameter (OBD) springs. They have the travel of the Swifts, but the pricetag of the Eibachs - definitely the best bang for buck on the market. More on this later, but that's the overview.
-StopTech: Their customer service has been nothing short of outstanding. They put a lot of thought into their products and they offer great brake tech on their website. I bought my StopTechs used - the previous owner did track events on them for four years - and they are still going strong after all that abuse. Eric has been great to work with.
Onto the build!
