Where's Wally

[ArizonaBOSS]

Rear Camber was 1.2* from the factory, very close to the R Track spec of 1.25* so I didn't change it. Spec for 350 is 1.00*

Rear tire wear looked even, but we'll see what happens when pushing harder. Of all the alignment settings, rear camber is the most difficult to adjust -- the bolts are well buried.

Also my Rear Toe was 3/32" In. Both the 350 and R Track specs are 0.30" (11/32") which seems really high -- I didn't alter mine, and didn't experience any instability under braking. Anyone @ArizonaBOSS @VoodooBOSS @fuhrius @Moto @voodoo child21 have any insight on rear toe -- this new fangled IRS is new to me ;D

In general, for an IRS car, the "fast" setup is a little toe-out in the front suspension, a little toe-in in the rear. Toe out in the rear is not good.

Rear toe would be best at 0-.062 according to Vorshlag on a IRS

I think the difference in the factory recommended camber settings is more tire than suspension dependant. Regardless they aren't going to be relevant for many of you.

Agree, tires will be the biggest variable, and we are only at the start of the learning curve....

Thanks -- makes sense.

Now that makes sense -- I'd mis-read the spec it's 0.3* in not 0.3in

it's interesting that the front toe settings are quite different. the gt350 has toe out of .1 degree and the r has toe in of .06 degree.

That actually makes a lot of sense, Althought it's the same car it's an apples to to green apples situation. damn, I need my GT 350 :-[

A good majority of these cars will be on aftermarket track wheels with R compound tires on the track so the Ford alignment specs for the OEM Michelins go out the window to a degree. I would bet the most popular choice will be R7s for both GT350 & GT350R owners meaning the alignment specs will be similar. Realistically how much difference is there between .06 and .1 degrees of toe anyway? I have generally run zero toe on the front since I still drive mine on the street to preserve the street tires.

 

[Black Boss]

Based on the fit of the R7's, I ordered some more "Purple Crack". Comparing the wear pattern after 5 cycles (2.5 hours) with fresh rubber, I'm happy with 2.0* of camber for the time being:

@VoodooBOSS @fuhrius Sorry for the delay on tire info. Here's a shot of the front L & R PSC2's after 1 day (about 2.5 hours) of track time running 1.75* camber:

Nick, On the stock PSC2 tires would you recommend the 1.75* or 2* camber.

It's early days, but if I were driving to the track, I'd go with 1.75*, and check wear mid day. Trailering I'd go with 2.0*.

 

[VoodooBoss]

Nick did you add TPMS to your second set of wheels? If so what frequency are the sensors. I see 433 and 313 Mhz sensors available from RoushYates as take offs. Also what stems did you use, the DILL-VS-925B?

 

[Black Boss]

Yes I used TPMS. Ford Part number is: FR3Z1A189A

If you shop around you can pick them up for about $21 each and they include the valve stems. They auto-sync and seem to provide real time pressure data for each wheel.

 

[VoodooBoss]

Thanks. Did they come with metal valve stems?

Yes. This was the best pricing I found:

Thanks I just ordered 8 of them.

Wally got dressed for more Track time:

8) Did Track Day Solutions make those for you? Also which lug nuts did you use with your Forgestar wheels? I'm looking at these due to the recessed nature of the GT350 front wheels.

Nice touch. 8) I need to order some graphics for mine as well. Where did you find those?

Those do look nice. Be sure to give Pete a shot at Track Day Solutions. He can also custom cut anything you need and has done all my graphics.

Can they do magnetic decals? I like these.

I used these Titanium 12 point lug nuts. 3.5 oz for titanium. 12.5 oz for the stock
