the advent of the new M7 COs has sprked some interest in me re suspension...... when I bought my PSS9s and had the car corner balanced, I thought, I am done...... while the Koni yellow/H-sport set up was great for fast driving on smooth roads..... I bumped my head too often on the liner.... The PSS9s gave me a more compliant ride, lowered the car and I have been very happy. The M7s come out and i talked to Dave (DDM) and he really likes them...... he has driven my car and tried some different settings and still prefers the M7 units.... his comment to me was "for the $" Dave has Ohlins on his Miatta and really likes them.

In discussing the "high end" I have been intrigued..... what is the best set up for a steet car driven aggressively at places like the Dragon......regardless of $

pure track cars have no interior.... this is not what I am talking about.....

 

Regardless of money? Most of these will require you to do a lot of engineering, some may require fabrication, and all will require a lot of effort testing and tuning. Any of these could be tuned to be the ultimate street suspension, BUT they will ALL require more maintenance than say, your PSS9's!

Moton - which will take some custom work and sorting out - oh, and a wad of cash.

JRZ - Spec your own stuff and drop them a check for a lot of $.

White Power - Spec your own stuff and they'll make anything for a lot of $.

Ohlins - Spec your own stuff and they'll also make you whatever you want for a lot of $.

Leda - triple adjustables + gas = big $

DMS 50mm units - well north of $5K, IIRC

That's just a few... there are more out there, too - really, really high end. From what I can tell, there are very few people that would pay $4-6K for a coilover setup for a MINI, unless they're going Grand Am road racing.

 

This question cannot be answered. The notion of quality and best is highly individual, you know this. My Megans for the most part feel fine on the street, but lose composure on the track. Matching spring and damping rates, slow and highspeed pistion speed afftect how these all work and feel at different speeds and at threshold handling.

Camber adjustments affect comfort, as do wheel offsets...up front for example as well as a host of other 'things'. How do we calculate all the tedious differences into each individual component? Not easy.

I do not like progressive rate springs. Some folks do. I track my car...if I didn't, I might find a progressive rate setup under my rig.

For the street, keep your spring rates under 300# front and rear, use a barrel type spring so it compresses into itself retaining as much travel as possible and look for a setup designed in house - spring and dampers. Avoid aggressive camber anlges, retain stock bushings and swaybars and yer set. The track is wide open.

Some folks, K-huevo, use JCW springs and Koni FSDs with great success. He basically stated to me the ride is great, but not enough spring or control for track work. Probably a really nice street setup for not a lot of money.
