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? |

Hey James! Good to see you around. That car is absolutely GORGEOUS!!! You should probably just call me one night and we can get you pointed in the right direction. I like setting up 3rd gens...
I'd avoid the coil over conversions. You can do the job with Ground Control stuff and not have to get too creative. Single adjustable Koni's work great on these cars. Get the 3rd gen front and rears (the monotube rears are quite good, and I like them better than the twin tube 4th gen shocks). 36mm hollow front bar (or a 35mm solid). 21mm solid/22mm hollow rear bar and I'd run a 1,000 in lb front with a 225 in lb rear spring (give or take). I found it ok on the street with that setup and my old 3rd gen was super balanced and easy to drive. Toss in a set of camber plates from Hotpart and you're done (and a good PHB, preferably with rod ends). |
