I'm still very convinced that a good shock absorber will eliminate loads of body rolls and improve the handling significantly, even more than changing tire.
My experience with my 2000 Galant which I still own up till now are:
- In the beginning loads of body roll, no traction because of it and can't accelerate properly. Ride's very smooth like riding on flying carpet but can't take turns. Problem with the tire as well since i bought it second hand and got a chinese branded tire (dispose of it immediately, very dangerous for safety on the road).
- Changes made:
1. changed from 15" to 16" with new michelin energy saver+, improved traction for cornering, but don't improve fuel nor getting worse so very little effect on fuel consumption a wider tire.
2. changed the shock absorber to koni sport yellow. Leave the setting to the factory mode softest. Rides improved significantly, Feeling every stone and uneven on the road now. cornering improved significantly, very little body roll. Acceleration from stop improved dramatically since the car' don't get to 45 degree position when hitting the gas, instead still on level with the ground.
3. left the spring untouched.
Still need to do: changed the tire to pirelli, source tells me it's even better than continental, soft ride but loads of road grip.
