Do not use your stock lug nuts. Get the chrome/locking ones from MustangTuning.com. Got my wheels and lug nuts from them. Great fit and compliment the wheels very well also. Plus they lock too!
I believe your talking about the PFRacing.com Carbon Fiber Front Spliter for the Saleen Front Bumper.
I hae heard of the Carbon Fiber Side scoops, but IMHO, I think you'd be ruining the total "look" of your car if you went with these.
For the PFRacing Spliter Start a thread in the Saleen...
Check out...Tirerack.com....and read the reviews. Great tire and great price from what I hear...my 295's are on national backorder. But all in all, I am sure it will be worth the wait.
