Mad Hatter
Gotta go Faster
My race buddy and I both have the Cortex extreme coil over setup with the Konis and race springs with 600# front and 400# rear. I thought I would try to give a write up on the difference they made. Still a rooky to the race world so excuse the terms etc!
1)First thing you notice is how solid the suspension feels compared to P springs, stock Boss shocks. Firmer but more controlled with little problem doing double duty on the street. Set the ride height to pass some speed bumps and parking spots. What a relief!
2) Changing ride height is very simple and can be done at the track easily while changing wheels. Front Konis are quick and simple to adjust. Take care with the rears since they have to be adjusted with the coil overs out of the car.
3) It was my first time with the coil overs so I did very little adjusting. First two session I kept the nannies on and had lots of braking problems and it felt like the car was trying to take over the driving. very uncomfortable as the computer freaked out! With everything turned off the car was much better and quicker. It was controllable at the limit, giving more confidence to push harder. Even when you over cook things the recovery was quick and agile. Will have to set my sights higher as the car is just easier to drive.
My buddies GT has had more time with the same coilovers and runs in a different category with R7s. Fine tuning his car was great. With the LCAs in the lowest position for traction the car was getting light in the rear on a steep down hill section under braking. By lowering the rear of the car another cm you can fine tune the angle of the LCA and the car improved right away. The GT runs with out a rear bar.
Next time out we should have the cars corner balanced and ride height set quite a bit lower. Got the bump steer kit ready to go.
This has been the single most expensive change to our cars but we both agreed that the Cortex kit brought the car to a new level and, apart from tires, was the most important change we have done to the car. So far very happy. I will try to put some videos up of the two cars at work later
