Just so you know, I'm not looking to build some killer SM2 914. I just like autocrossing my street car and the old club that was REAL loose with the rules lost their site a couple years ago. Now I'm looking at potentially running some SCCA events and since I used to work registration for a couple different local clubs I hate it when people have no idea what class their car can even run in much less how their mods fit in the different classes.
From the SCCA rule book chapter 16, Street Mod & SM2 16.1 G. Subframe connectors are allowed as per Street Prepared (15.2.E). 15.2 E subframe connectors E. Longitudinal (fore-aft) subframe connectors (“SFCs”) are permitted with the following restrictions: 1. They must only connect previously unconnected boxed frame rails on unibody vehicles. 2. Each SFC must attach at no more than three points on the unibody (e.g. front, rear, and one point in between such as a seat mount brace or rocker box brace). 3. SFCs must be bolted or welded, but welding must be to the OE subframe stampings, not to the floor pan in between. 4. No cutting of OE subframes or floorpan stampings is permitted. Drilling is permitted for mounting bolts only. 5. No cross-car/lateral/triangulated connections directly between the driver’s side and passenger’s side SFCs are permitted. Connections to OE components such as tunnel braces or closure panels via bolts are allowed and count as the third point of attachment. No alteration to the OE components is permitted. 6. SFCs may not be used to attach other components (including but not limited to torque arm front mounts or driveshaft loops) and may serve no other purpose. Seems to me the Brad Mayeur kit and clam shells violate items 1,2 &, 3 and the Engman kit since it goes across the fire wall and joins the two sides adds item 5 to the list of reasons it is not legal. Let me know how you interpret these rules. Kelly |

Unless you expect to be competing nationally, or ruling the roost locally, I wouldn't worry too much about it. It sounds like your car will not be anywhere close to the limit of the rules in preparation. If you start winning locally, maybe you should move into another class, or if you plan on competing at National Level events, then pick a prepared class. But for just having fun locally, I say run it in SM2 and have fun...
yeah, the cage can be a big help... -Josh2 |

But for just having fun locally, I say run it in SM2 and have fun... That's what I am doing in SM2, just enjoying running. I don't come in first, but definitely don't come in last. There is a kid in a 350Z I usually edge out by .5 seconds or so. I tell him I have 115hp and it just pisses him off. Good times, good times... |
