Here is my own subjective observations while instructing in other peoples cars. My interest is focused on ride quality, performance and handling and I don't really care about car show quality fender well gaps etc.:

1. Eibach lowering springs- Too low and introduced alignment and bump-steer issues. Difficult to get right.

2. M030 ROW- These cars always feel good with a balance of street driveability and better front grip/easy rotation for performance driving. The ride is firm but still good.

3. PSS9s- Very dependent on setup. I have been in cars with well sorted PSS9 suspension that felt great and cars (usually owner installed) that were scary, unpredictable and awful. I don't recommend a DIY install. Set to full soft for street use and the ride is very good.

I hope you find this useful.
