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?

as I understand it, 1 way in the front is just better for our applications

Yep. Ive run it with Stock, disabled, ACD Tuning, and now ER tuning. Nothing helped the lift turn-in on the ACD when the front diff is causing it.

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.

To be clear, I'm not talking about turn entry. I'm talking about when you need line correction or you have decreasing radius, or just in general need to lift turn. Goal isn't to try and unstick the rear at that point but to have the front bite.

interesting. is the 1way though a big improvement over the stock helical? worth the hassle?

If you want something just strong and reliable, the Wavetrac is great. But it was one of those things when I put it in I could really tell. If it was negligible or worse, I would have just swapped back to the Wavetrac cause it was a known constant.

Stop drinking that cool aid. Santi and I have already told you that offset doesn't matter.

Thanks. Will look into the seats, not quite ready to lose the a/c yet. The greddy ti js awesome. Too bad they discontinued that. Tomei is the only option these days.

Good to know. Will see if I can find this info somewhere.

Couple other questions. Can the rear wiper be romoved along with the washer tank? Is the Evo Dave fender mod legal? And is this front lip legal?

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.
