So I am just begining to see why people always sa race cars are never done. I just ran my first autocross on track tires (Nitto NT-01s) and now my previously perfect handeling car lifts front wheels way into the air. Corner workers were saying as high as six inches!!! Now I am NO expert but this leads me to believe that there is still a considerable amount of time to be had if I can keep the wheels on or alot nearer to the ground. My question is how stiff to go in the rears. I currently have #140 Weltmeisters on the back and stock front torshens with a H&H 19mm ajustable front sway bar set one hole from soft leaving two stiffer settings (four holes total). I am thinking #175 or #200 2.5inch springs on ajustable perches. Any suggestions? Will ajusting the front bar to full stiff be enough to counteract springs this stiff? This is for a strictly autocross car that only gets driven to events and on the occassional sunny day. Also it has a six pt. cage.
Any input will be appriciated since I would only like to buy one more set of springs. Attached File(s) ![]() ![]() |

Right now I am running probably the cheapest suspention upgrades that one could do. The rear shocks are red Konis, the ones that you have to remove the spring and fully compress to ajust, that came on the car when I bought it about four years ago. When I put on the #140 rear springs I ajusted the Konis to full stiff because I figured they would need to be firmer to compensate for the stiffer springs. When get new springs I will definatly buy new shocks because I found out the hard way why they reccomend using three of the skrew type spring compressors instead of two. Dentist bills cost way more than a new set of Koni Sports. The rear bushings are Elephant Poly Bronz so they sre probably not the problem. By the way if any one is considering these bushings I highly recomend them. They inproved the ride quality over worn stock bushings and I was able to install them without disconecting the brake lines. The only downsides are that the grease fitting holes a hard to drill, broke about five, and tap and the new bar bolt thing that the bushings rotate on is not hollow like the original one so it is about twice as heavy.
From the sounds of things I should save my money and get 21mm front torshens #250 ish springs and a full set of Koni Sports to replace my questionable rear shocks and my front KYBs. By the way I found 3.75 inches at the front jack points to be to low. I blew out the drivers shock and even now with new KYBs, were new in the box left over from another project not my first choice but made it easy and cheap, and 4inches at the front jack points I only have about .75inches of travel before my shortened bump stops start to work. Thank you guys for all of your imput on the black art of suspention tuning. |
