Yes but what about when you sitting in the car a driving Iam sure you weight at least 190 so theres extra almost 200lbs which equalls to 4000 and if you subs in the rear add another 40 or 60 depending on speaker size.
And 4000 to 3600-148lbs from SRA well you do the math. But yes if you have some Mickeys or some good DRs fact is you can launch the shit of the car with SRA.

I say unless you're REALLY serious in whatever form of racing you're doing, build what you have, whether that be the SRA or the IRS. If you're really serious about 1/4 mile, eventually you'll want the SRA for the added strength. If you're really serious about handling, eventually you'll go to the SRA for the better geometry (unless you're on really bad surfaces, then you may want the IRS for it's better roadholding ability on the rough).

Pardon my ignorance, but are you saying that the SRA is better than the IRS for handling on smooth surfaces? Sorry but I've spent the past 5 years driving mountain roads in Southern Cali & it seems to me that if 2 cars were set up the exact same way an IRS would kill an SRA because it could put a lot more grip down when cornering; hence making it able to corner at higher speeds without sliding out

Yes I am. And were we talking about any car besides a Mustang, you'd be right. But a torque arm Mustang will outcorner a Cobra IRS car, all else being equal.

What about on a foxbody?

Oh, and let me threadjack and say what a GIGANTIC FKING RATTLETRAP my foxbody is. Seriously. I'm hoping the SFCs tone SOME of it down. (yeah, yeah, I haven't got my SFCs installed yet... they're just sitting in my garage collecting dust I'm working on it!)

with the exception of a few cars (mustang being one) EVERY road race car has IRS, for good reason too. if you want good info on the IRS go to Full Tilt Boogie Racing Homepage that'll answer any of your questions you can possibly come up with in reguards to the IRS/solid debate

Yeah, a well-designed IRS will outhandle even the best designed SRA every time. The issue with Mustangs (and I do believe that is the point here) is that the Cobra IRS is *not* a well-designed IRS.

For the '79-'04 Mustang and only for the '79-04 Mustang a properly prepped SRA car will outhandle an otherwise similar IRS-equipped car.

I can vouch for Bruce's kit. I have it, LOVE IT. It is the best mod I have ever done on my 03 Cobra vert period. His kit has removed 99% of the wheel hop I ever had. Now the car feels like I'm riding on rails when I carry the car to an open track event. Love it! A MUST FOR ANY IRS 99-04 Cobra.
