Post SCCA G Stock Rule Clarification

Alright, help a guy out here. My rule book is AWOL and I have a couple quick questions regarding GS in SOLO 2. Is it legal to remove the silencer? Is cat-back exhaust legal (or further)? Are computer mods legal?
Please only reply if you KNOW the answers. I'm trying to whoop some Type R a$$, so don't get me DQ'd. Thanks all.

GS..

Silencer removal... not legal (13.10 A - The engine air filter element may be removed or replaced. A replacement element which is taller than standard may not be used to hold the air cleaner cover open. No other components of the air induction system may be removed, replaced or modified.)

Catback... Legal (13.10 E - Any part of the exhaust system beyond (downstream from) the header/manifold or catalytic converter, if so equipped, may be substituted provided the system meets the requirements of 3.5. Stainless steel heat exchangers are permitted only if the physical dimensions and configuration remain unchanged. Modifications of any type, including additions to or removal of, the catalytic converters, thermal reactors, or any other pollution control devices in the exhaust system are not allowed and the system must be operable. Replacement catalytic converters must be OEM if the vehicle has not exceeded the 5-year/50,000 mile warranty period as mandated by the EPA. Converters must be of the same type and size and used in the same location as the original equipment converter(s). This does not allow for a high performance unit. If the vehicle has exceeded the 5 year/50,000 mile warranty period, replacement catalytic converters must be OEM-type as per Section 13.

Computer... not legal. (13.9 D - No changes are permitted to electronic engine management systems or their programming)

Thanks KC. Got beat by a Type R on Monday and just wanted to make sure I was getting every edge I legally could. Dude was definitely fast - I'm no rookie and he beat me by over a second. Of course, I had only owned the car for a couple days. With a better alignment and a bit more practice with AWD, I'll get him next time.

Thanks again.

get some AGX struts, change your air filter and plug wires, and get some some race rubber. These are also legal changes.

LUME - Any filter other than stock is not legal.

Tom .. read the 1st line again.

The filter ELEMENT *may* be replaced. (Ie K&N, ITG, etc... panel replacement filters that fit in the stock location and are of the same size). Or it may even be completely REMOVED... not a good idea to remove it tho....

But you can't swap out the air-box and put in a cone filter, nor can you remove any of the plastic before the box.

Have you got R tires yet? Get a set of the 16 x 6.5 Legacy GT rims with some Hoosier 225/50R16's on it. That would be the first thing I do. Second is an alignment, do not just take it in and find that its within factory spec. Get as much negative camber as possible. Third, get a harness. Not the Schroth but a 3 inch 4-5 point camlock one to hold you in. Finally, seat time. Go to as many solos as you can.

Thanks all. R-spec tires aren't an option though, I'm running TGS (street tire). Can anyone share their alignment specs. I assume as much negative camber up front as possible with factory adjustments. What about toe-in, out and what about the rear?

Do a search in the suspension forum. I remember a post awhile back where a lot of the more prominent tuners posted their settings (Rallispec, Cobb, etc...) That might help you out.

SKR,
I use equal max neg camber up front, zero camber in the rear and 1/8" toe out front and rear. This way I can rotate the car with the throttle or the brakes.

Good luck, Mark

SKR,

Was it Evan Moen in a yeller Type R. If so, he's been rally racing for a few years, and is quite fast in autox as well.

Mark - nope it was Jeff Gunning in the Type R. I've been autocrossing for 7 years and this guy was SMOOTH. Oh well, I only had like 2.5 days of driving the WRX before the race. We'll see what happens next time.

STILL LOOKING FOR ALIGNMENT SPECS! Any others?

Check with COBB tuning... a friend used their specs and had some good results last weekend... not that he needed any help!

I believe it was 0 degrees caster and camber in the rear, and 1 degree caster and camber in the front, but don't quote me on that...
