Do yourself a huge favour
contact Rob at Needswings for a set of coil overs
yes they are a few bucks but they are adjustable and will give you the ride you are after

Real deal, these work, no bull. I and many others have ordered and installed them. If you have a special requirement, he’ll be able to accommodate it. I spun mine right to the lowest point and had to bring the car back up because I was rubbing inside the wheel wells and scraping on every speed bump

The range of adjustment is really impressive. You’ll spend more in time adjusting what you have than you will have to spend for a complete setup.
