Dell might be right re 8s - guess its track dependent ... But wing won't stay up under pressure w/o shims IMO ie it flexes

LVDell

Not smart to do that without the shims.

I've been thinking about putting a bigger spacer on top of 8 degree shim. Wing can incline more than 8 degrees. Mike

Nasty drag though, right? And what to balance the front?

I do not make this stuff up. Case in point. Hans has instructed for many years with the NER PCA and he has owned his GT3 since new. He is not only a very good driver, he has vast knowledge of the GT3. I have never seen shims on his car. BTW, he is selling this package, GT3, spares, and trailer. Asking $68K. The Cayenne is also for sale. $5k - the front differential is gone plus it has well over 100k miles.

Hey Dave - I'm sure you're not making it up for sure. And like many here I'm here to learn and in a few cases - not many - share my experiences if they might be useful.

I had my wing extended w/o shims and thought it was better than stock ... Until I noticed that with just a bit of pressure (by hand, not forceful) the wing would flex and drop. So I surmise that with 10+ kg of air pressure across the length of the wing, it is likely being forced down thus negating the added tilt. Also from the way the metal settings are mounted in the wing, I'd estimate there at cracking/dislocation risks to running the wing without the load spreading the shims provide.

Ps - I shd add my experience is based on my RS wing

I've definitely seen that combo towing down 95 before, good to put a name/car to the awesomeness usually going down the highway

Depends on the track Dell. At Miller - 4's on the stock wing give me better lap times on full track config. I lose too much straight-line speed with the 8 and give up too much cornering speed with out the shims.

Now for half-track configs, I run 8's!

I disagre with all this must do crap for GT3 specifically

Make sure you have proper safety gear, as you would in any track car

Next just get some R comps, and cup ducts

Then go dominate, or learn how to drive well enough that you can

I'll bet that is more seat of the pants than anything. I ran 0, 4, and 8 on both stock and RS wing. The jump in DF you will feel is going from 0 to 8 on the stock and then 0RS to 8RS (FYI....the stock at 8 is = to the RS at 0 in terms of DF). I compared data on all and I only lost a few mph on the loooooooooooong back straight at VIR with the 8RS compared to neutral but increased my speed in the high speed tight sections and lowered my lap times.

YMMV.

Don't need R-comps as a must have.

GTgears

A rebuilt LSD is a must have. Without it you're leaving +/-2 seconds a lap on the table.

^ Yep- what Matt said : ). Best mod I ever done!!! Mike

And it's a great safety device should you ever put a wheel or two off.

Installed the 4 degree shims yesterday and then drove it quite a bit yesterday evening and noticed the car isn't as "nervous" feeling. This was pretty surprising, since I didn't think the change would effect it much at "spirited" highway speeds.

Still need an alignment, but this gets me closer...

Mike, don't forget if you are running the shims with the extra DF, you need to run the cup lip to balance it out. The cup lift reduces lift in the front and also looks 100% better than the stock lip. It's cheaper too!
