Over the weekend I took the Camaro out to the Midwest Musclecar Challenge (www.midwestmusclecarchallenge.com/).
I had a blast, however I now am much more humble about my driving ability. I have the power, I have the brakes, now I am ready to begin improving the suspension on the Z. This, is where you guys come in. Usage Street - 1-2 times a month to work or cruises Track - 3 or 4 track day events per year Autocross - occasionally Details about the car: 1991 Z28 hardtop LS1/T56 Stock rear with 3.42 posi C5 corvette front brakes, factory 91 z rear disks (HP+ pads and ATE superblue fluid) weld in subframe connectors Spohn tubular K-member Suspension boxed rear control arms solid panhard bar Factory 91 Z28 front and rear swaybars (not sure of size) Eibach sportline springs (fronts cut 1 coil to level ride height after LS1 transplant) no name shocks and struts from prior to 2003 when I bought the car. Wheels/ tires 18X8 (245/40/18) front 18X9.5 (285/35/18) rear street tires. 200 treadwear Be aware, I am not a rich man. changes only come slowly when I can scrape together extra cash. I need a priority list to tackle for best bang for the buck. Questions: 1) I know I should replace the shocks/struts. should I jump straight to double adjustable or is there a less expensive option that will help? 2) Have I totally screwed myself up by cutting the coils on the Sportlines? What rates should I target? 3) Should I skip coils and struts and convert to coil overs? 4) Can I have a good setup for both track day and autocross without changes? |

I thought I would update the group.
I have the Memphis track Event this weekend. (autocross, HPDE, and drag race) Changes for this event: 1) Swap the fleabay "racing" seat for a Sparco Evo 2) Added a power steering cooler since I was puking fluid out the cap after every session. (I know the best solution is a turn one pump, but they are on back order) 3) Re-route the clutch line off the header & flush/ fill the clutch system. I am thinking about attending a SCCA autocross Test-N-Tune event Saturday May 31st. If I do then I believe the next step is to purchase and install KYB AGX shocks and struts. that will blow my budget for a while. It will be nice to have plenty of runs to change shock settings and see how it affects the car. I do believe this will be a LONG term suspension tuning project. I guess I need to start finding different size swaybars and possibly springs. Mostly I need to get more seat time! I think autocross may be the cheapest/ only option I have to improve. |
