Comfort is a factor of three things.
1. Personal opinion.
2. Springs (not just spring rate)
- The spring rate split with heavier wheel rate up front, means that the rear of the car is under-sprung and causes a lot of the discomfort riding over bumps, with the rear bouncing around in response to these bumps.
- I run 400 in/lb springs in the rear with shocks that can handle the bumps well and provide the correct amount of rebound, the ride is taught, but also very forgiving, and the rear does not bounce around.
3. Shock damping curve and other valving abilities
- Low-end shocks are all about the same, and do not have the valving built in to blow off harsh bumps (high speed blow off)
- When you purchase "coilovers" a vast majority of the cost (should be) in the shocks.
- To that end, you can get comfort from shocks like the Ohlins Road and Track and I believe the KW V3, and other boutique shocks.
If you can't afford that kind of shock, then get your hands on some rebound adjustable shocks (digressive valving if possible), get the spring setup I mentioned, keep the front springs if you want, and turn up the rear rebound until the rear of the car does not bounce more than 1-2 times over a bump.
Then get 17 inch wheels, or 16 inch if you don't have PP brakes, and enjoy the "relative" comfort.
