One other thing you get is the ability to improve the front/and rear geometry. The front inside pick up point is raised 20mm with the 935 style stuff. In the rear, if you use raised inner pick up points, you can use the raised front outer spring plate mount as well. Obviously doing this in the rear requires considerably more expense to purchase and weld in the raised inner trailing arm mounts.

Spend your money where you want it. Some update/backdate bodywork at considerable expense for no performance advantage, some dump money into questionable engine mods, some go overkill on their suspensions, some even upgrade stereos...... you get my point!

Coil springs are cheap if you want to change the rates someday which is also nice.

Like I said in my first post, they certainly not required but I am very happy with my set up. My car does see a fair amount of track time but I do use it on the street as well.

Cheers
