wildcatgoal's Build - 2016 DIB GT PP

This is what my 305 square setup looks like, in case anyone wants to know.

SVE GT350 19x11 ET 50. 20mm spacer up front. Can use a 25mm spacer, too.

Worth noting, my car is only .75" lowered at all 4 corners. I run -2.5 camber up front, -1.9 in the rear.

I have no idea if a lower car could handle this setup or not. The 305 tire is approx 5mm away from the strut, maybe 3-4mm. It never rubs. It does contact the inner fender lining a little but nothing I care about.

305/30?

I wasn't there, but my friend was. He's in the Radical you passed at about 4:30. It was his first time there and he really liked it. Were you at Road Atlanta last month?

Yes, I was at RA with JZilla also last month.

With the the longer studs and spacers do you torque your wheels to a different spec than the OE studs?

The wheels I want come in the same size and offset as what you have as well as a GT350 spec. Which would be the same as if you ran a 25 mm spacer. In general I'd like to avoid the spacer, but its getting close to hanging out there a bit much.

Another question, do you keep the -2.5 front camber all the time or just for the track.

Thanks in advance

Same torque spec for spacers and longer studs - 148 ft lbs.

Same torque.

Yes, I just leave the Track alignment all the time now. I have very little toe so the tires seem to wear fine, but I also don’t daily drive the Mustang anymore. That’s what 2012 Toyota Camrys are for. . I used to get an alignment back to stock-ish specs after events but that is a pain in the ass.

Informative thread, thanks. I align for dd at 1.5 neg squared and am on 255/45/18's.
I need wider wheels to use wider tires. Running Bridgestone S0-4 pole positions, not real happy for the $195 a tire price as they spin too much.

Someone told me those tires are more appropriate for AWD cars as they have lateral grip but not much acceleration grip. Could have been a bunch of BS... but those are too expensive for their reviews so I've never considered them.

Where are you getting this information? I was told 105 ft/lbs max for arp studs.

Our prior discussion as well as one I had with an engineer buddy of mine about nuts and bolts in general are what prompted me to ask him.

I did look on ARPs site and the generic max for a 14mm bolt/stud of this tensile strength is 184.

IIRC the maximum torque to apply to wheel studs is 10% below yield to allow for expansion and contraction though heating and cooling.

150 ft/lbs is well under the below 10% of max threshold.

Depends if you are installing the 1/2" or 14mm ARP studs. I would not torque the 1/2" studs to 148 - big difference that needs to be clarified.
