It has taken me nearly 10 months to finally work out what the problem with the ride quality of the car was.
But I now have and have now sorted it!
The ride quality was terrible; crashy AND bouncy. It got so bad I really didn't like to drive the car.
I have BC coilovers on the car, so got the ride heights correct for the 'stance' that was required. But the ride was awful. I have spent much time adjusting damping force and tyre pressures, as I initially thought it was a combination of big profile 'balloon' tyres and 'racing' type shocks and springs.
I was getting to the stage where "I couldn't see the wood for the trees".
It was the front dampers. They were set miles too high in their mounts, so when the car was dropped onto them they were at full compression so there was no front damping, or shock absorbing. The tyres were taking up most of the damping, then the springs were doing the rest. Which made the car bounce like a manic space hopper and crash over every imperfection.
Luckily I don't think I have damaged anything. In my defence, the suspension instructions are terrible and the design of the front coilovers is a bit stupid (with a continuous thread all the way up the 200mm tube), so it was difficult to work out what the problem was. Especially as me and suspension set up have never crossed paths before!
But I've sorted it. It now rides like a 'normal' car. So the sale price has just gone up (a lot)!
