I had the Wavetrac front diff and just recently swapped it out for Mfactory set to 1way and 60% lockup (set with plate stack). Wavetrac is 1.5way so causes some binding with heavy engine braking and high steering angle. Which exactly when you are trying to lift and get the front to tuck in. I fought the lift turn-in for a few years before being enlightened to the likely cause.
Wavetrac is fine though, basically works like stock but much stronger. Great on track where steering angles and engine braking are much less.

Interesting...the car is only used for autox. So it sounds like the Wavetrac will cause some problems. Does yours have ACD?

good to know. my diff is a 1.5way, but very aggressive, and used to have some binding issues on turn in, largely due to the diff. after my ER ACD tune, which I'm assuming they set up so the center is completely open on turn in/off throttle, I can get massive rotation and yaw. rear diff fixed power understeer, ACD tune fixed turn in understeer. interesting that with a wavetrac it will bind as well.

There is a weight reduction thread hiding over in the electrical/audio/security (???) forum that has a lot of info, even if most of it doesn't apply to ASP it's a good read. The big hitters for us were the seats (NRG carbon...super cheap and light), cat back exhaust (greddy Ti, weighs like 8 lbs total compared to like 50 lbs stock), and the A/C (30 lbs).

I hope a replacement front lip wouldn't get you booted seeing the OEM ones are not easy to find. I'm getting my front lip installed today and never thought it could be an issue. I don't have the OEM lip but got an eBay polyurethane version seeing it's storonger and it will take a few cones.

Replacement lips, IIRC, are not ASP legal. Reason being you can get pretty liberal with the rules and it becoming a splitter if it was. Geoff Clark just had a missing lip after his broke because he couldn't use an Ebay replacement.
Also, washer tank and wipers must remain and functional in ASP. Need to go to SM to remove. Also, it was explained to me that it technically needs to be a proper level based on the min/max markings. All those rules exist just because things become a slippery slope.

I would say replacement lips are legal if they are the same shape as stock. the one pictured is not legal because of the extra splitter area poking out.
you can update/backdate to the RS rear window which has no rear wiper but technically you can't just remove the wiper assembly. now whether someone would protest you for just removing the rear wiper but not changing the glass...i dunno. I wouldn't protest but that is just me.
cannot remove the washer tank. it does not have to be full of water and can be completely empty. (Dallas, there is no minimum markings on the washer tank)
evo dave fender mod is another one of the technically not legal things but would be a weenie protest. you're allowed to modify the fenders for tire clearance but you're limited to things that are outboard of the hub face. the fender mounts that gets extended in the evo dave mod are inboard of the hub face.
