Bury's indoor meeting on Sunday was a big learning curve for me with the evo. The way I drive is smooth in to the corner and fast out of it. One of the handling traits the car has on high grip is the rear end squatting/collapsing hard and lifting the the front inside wheel, this happens when coming out of the corner and getting hard on the throttle. To stop this happening it's normally a case of going heavier on the rear roll bar and spring, smaller hole piston and/or heavier oil in the rear, shorter and lower rear link to make the car square up faster, more or less anti squat 'depending on make of car'.

After changing all of these settings from one extreme to another, it made no difference, and the car would still do it. So that now tells me that it's a power/drive train transfer problem and not so much a suspension issue. So I came down in the centre diff oil to 20k and it really started to improve it, for the Final I dropped it down to 10k and again it felt better, but it was still there. After reading posts from people who retro fitted a centre diff in the Sworkz 104 ek1, most said that they found the same thing happening after fitting a centre diff. I found that on the slippy section of the track 10k all round felt really good, but as soon as I got on the carpet I was loosing a lot of time as I couldn't drive it the way I wanted to.

So now I am trying to fit a slipper clutch to the car, and then test it this weekend and see if that resolves the issue for me. I do think the front end is over damped and under packed with the standard kit pistons and needs a smaller hole piston so we don't have to use such heavy oil in the front, it also needs a much stiffer front spring compared to the rear, as it helps keep the front end more level over jumps and bumps.

I will post up my findings after the weekend.
