I'm not trying to be a smart ass but the right answer might change my current plans for the Cavalier. Can this line in the IHRA rulebook be interpreted to mean that I can legally use my Vega based(stock) Jegster(aftermarket) front suspension? Seems like it conforms to both so if it's not legal - WHY NOT?  |

I think if you look closer at the line above
"STEERING-May be relocated. New Crossmember may be installed. STOCK TYPE STEERING AND ARMS REQUIRED."
There's your kicker Don. The aftermarket suspension they are speaking of would be the FJ Smith style Strange Struts. PRICEY!

That just leads to MORE questions - Does that mean the Cavalier lower control arms would have to stay? If FJ Smith figured out an expensive* way to make that happen why would his tubular control arms even be legal?
If GM produced Vega control arms and S-10 spindles why are they not considered "stock type"? Now the best question of all: How the f**k is someone supposed to figure all this out from only two lines in the rulebook?
FJ wants $1595.00 + $275.00 for tubular control arms* Geez - a complete Jegster chassis with full roll cage, frame rails and everything is only $609

Last time i Looked at his site, I thought only the modified stock arms he sold were legal. That may have changed. As for the cost associated with the parts, Welcome to HOT ROD instead! lol

The front suspension requirement is only one of the rules in the way of competing in SS/GT with this combo. Unfortunately the Jegster chassis under a Cavalier is not compliant with the rules.
The SS/GT rules say in part:
Requirements and Specifications for GT Front-Wheel Drive Conversions are the same as those for Super Stock...
Referring to the Super Stock rules provides this additional info:
FENDER SPLASH PANS: Must be retained, may be trimmed to allow 2” clearance around headers.
FLOOR: Stock floor mandatory. Area from front mount of rear spring on leaf spring cars, or front mount for lower trailing arm on coil spring cars, to rear of trunk may be sectioned in width to allow narrowing rear frame. Any protrusion in trunk may not be
higher than top of stock frame rail.
INSTRUMENTS: Full stock dashboard, including instruments, wiring, fresh air ducts and controls must be retained. Tachometer, pressure gauges, acceptable.
FRAME: Frame or sub-floor must be stock for body used. Subframes on unibody cars may be joined under car. Maximum size material to be used: 2” x 3” x .120” ms or .083” cm. Round tubing may be used to join subframe in straight line extending through car floor with floor completely welded to frame. Rear subframes may be moderately altered for tire clearance. (see TIRES). Rear subframe may be constructed of 2” x 3” rectangular material with .120 ms or .083 cm wall thickness or 1 5/8” x .083 cm or .120 ms round tubing and must be installed at original height location. Cross members may be added for traction bar and shock absorber mounts. See General Regulations.
WHEELBASE: Must retain OEM wheelbase plus or minus 3/4”, and width for car body used per manufacturer’s nominal specifications. Maximum variation from left to right: 1 inch. Alterations to wheel base, front and/or rear overhang, relocation of wheelwells and/or axle are prohibited.
At this point it's clear that modifying the Jegster chassis to fit without altering the factory floor would be more work than fabbing a car chassis from scratch for SS/GT.
Your other question asked about the term "stock type". Both NHRA and IHRA use this term frequently in their rules. Typically they are fairly restrictive in the interpretation of this term, and "mixing and matching" is held to a minimum. One exception is the use of manual steering boxes from S10s and Vegas on other GM products.
Don, I hope that this clarifies the SS/GT FWD conversion requirements. Sorry that it isn't an option for your Cavalier project.

That clears it up - thanks. But I'm not really surprised. I sort of knew that the cheap approach wouldn't work or there would be a ton of GT cars out there with a Jegster chassis. By cheap I mean $600 for the entire Jegster chassis/cage as opposed to $1600 for just the FJ Smith front frame section.

You're welcome Don.
The most cost effective way to get into Stock/Super Stock racing is to purchase a turnkey car, and even when buying them at 50 cents on the dollar the SS cars are expensive. However, if you're willing to consider a lower class (ie slower) Stocker there are plenty for sale for less than $10,000US, and if you are open to a front drive car or an "oddball" combo then you can get one for as little as $5000US. That's dirt cheap for a turnkey competitive race car! The only other major expense would be getting it home.
