Dell, I'm installing the RS wing and I saw your post seeking opinions on the 4º vs. 8º shims. What did you decide? What has your track experience been? Did you try both?

Any others with shim opinions, preferably with the RS wing, please chime in.

Also, here's a cosmetic question. My car is black. I'm debating whether to paint the shims black or Guards Red. My thought with respect to red is that it would be a subtle accent that would tie in with the red brake lenses, red brake calipers and red belts. Opinions?

whether you use 4 or 8 degree shims you should balance the car with the cup front splitter (Austin at TRG)...the shim angle should be determined by the track you are on...the 8 degree will give you significant rear downforce (good for high speed sweepers) but will also add additional drag if the track has any long straights...I have found good balance at LS, BW and WS with 4 deg and the cup front splitter...you should try both and decide....the shims are cheap...they are also a fugly color so you will want to do something with them...if black you won't see them...don't know if you want that small amount of red showing...here...you can visualize....

 

I have the 8 degree shims with the RS/Cup splitter currerntly. I give up some speed on the long back straight but it is a compromise I am willing to make so I can be more planted on the high speed (140+) sweeper on the front straight. I am going to order a set of 4 degree shims so I can compare and capture some data to see what (if any) difference there is.

FYI....the shims come in RED! I painted mine yellow. I'll paint the 4's black so I can easily tell the difference.

 

I painted mine black to meld with the RS wing.

 

Sounds like 4º for street and home track, PIR (no high speed sweepers),and 8º for Thunderhill and Sears (high speed sweepers).

I do have the RS splitter from Austin.

Now I only have to decide whether to paint 'em red or black.

I'd paint em black. Since they come in red plastic you could at least see what it looks like red.

 

This sounds like a very good idea. My 4 deg will remain black, and I'll do the 8 deg in yellow.

 

...and together we speed yella fellas will rule the world!!!!!!!

 

Read my sig!!! When I say "SLOW," I mean "SSSLLLOOOWWWWWWW!!!" At my age, I gotta take it easy as proven by my recent off of my motorcycle.

 

Well at least the rehab of getting back up to speed is fun

 

Could be, but looks like I'll need to wait even longer before I can rehab. Had a doc appt today because the ankle isn't healing. He referred me to a foot specialist to see if I need surgery. If I do, I'll probably have the shoulder done, too. That means NO track this year at all. I'll really need to work getting up to speed then.

 

damn, you got to take better care of yourself, joe.
both my rotator cuffs are torn.
btw, if your car needs exercise on track, you know who to ping

 

Are "rotator cuffs" like CV joints? Hell, NAPA probably has the parts to fix that.

And I'll be glad to let you exercise my 996GT3 when you let me run your 997GT3!

 

you are right, "my" CV joints need replacement, but doc wife says that if they cut me open, they can fix the tear but will f*k something else. her ankle has had 4 surgeries for the SAME problem.... surgeons... what do they know

sure, you can have a go on my 997. better fix yourself up first.

 

That's 997GT3RS... Already driven a couple of "plain" 997GT3s, and while very nice, IMO, not worth the extra $ over my 996GT3.
