By 1985, it was becoming apparent that there was a pulse, no matter how weak it was, coming from Detroit. After about a decade of slab-sided, softly sprung sedans that inspired exactly nobody, “personal coupes” that weighed in at over two tons and measured out at least as big as a 1990s cop car, and engines that were strangled, neutered and asthmatic, something was changing. Chrysler might have left the rear-drivers to the cops and the old folks, but they were cranking out sporty little front drivers that actually brought a punch to the table. Ford’s Mustang might have been on and off the death watch list throughout the decade, but with the return of the 302 V8, the scrappy little Fox suddenly had a bit of a bite. And then there was the Camaro, especially in it’s swoopy IROC form. Small block Chevy, ever-tightening suspension, and the perfect 1980s looks had a generation’s imagination captured. And IROC actually meant something. Unlike RPO Z28, which simply meant “sporty Camaro”, IROC stood for International Race of Champions, the racing series that picked up and ran with the third-gen Camaro body for years. Wherever you looked, there was a third-gen Camaro racing: IMSA, SCCA, Trans Am, NHRA all had their versions.
The basics for this Camaro are predictable: a Robleo 310 and Super Tex four-gear make up the powertrain and the rear axle is a Ford 9-inch with two gearsets included in the deal. Unless you are planning to make YouTube videos for the sole purpose of doing the impossible, putting this thing on the streets isn’t going to happen easily, if at all. Not that we’d discourage your, of course. Instead, this is the racing vehicle you really need to look at. Instead of building the hell out of a street car and finding out the pitfalls of creating a do-it-all racer, maybe a race car that was built only to be beat on is what you need instead. You can still say you have an older Camaro!
Or, you could spend 1/3 of the money and do the same thing.

You hardly need that much race car to kill on autocross. That much money invested sorta takes the fun out of it.
Race cars are cold hearted beasts and do not like to autocross. Temps for brakes and tires do not come up quickly, that’s why they make autocross tires and track tires. Lockers do not like autocross in the rear, too tight and slow. This is an open track car.
You are speaking out of school, I great number of the fast CP Solo cars run \”Lockers\” for diffs and they are quick.
