GT350 Front Camber Adjustment

I had bought a set of MM camber plates that I was planning to install. However it turns out that there's an alternative. Ford sells service bolts that are smooth and a slightly smaller diameter than the splined OE bolts:

I used a micrometer to measure them today -- the service bolt is 0.4mm smaller.

Here are the part numbers. Bolt: W715295-S439 Nut: W520216-S441

The service nut is Nylock, unlike the OE nut

I plan to install once I've finished the 1,000 mile Break-in -- 185 miles to go!

Not to wake a sleeping dog......but.

What alignment settings are folks using?

The 350R is coming with Ford caster camber plates. Dealer will be installing. Just need the specs.
 
You'll probably get lots of advice, but the actual answer is "it depends". If you're going to run the extremely stiff OEM CF rims, then you'll need less camber than you'll need if you throw on a set of lightweight alloy rims. If you're going CF, then start around the settings that Ford puts in the owner's supplement (6.92* front caster, -1.75*F/-1.25*R camber, 0.06*F/0.3* toe-in) and tune from there based on tire temps.

Note that the MPSC2's have different tread rubber on the inside and the outside - the outside wears faster, even when the setup is perfect.
 
I think it's safe to say that you'll need more camber, but I don't know how much. I'm sure someone on this forum knows and will chime in. Congratulations on the new car, by the way!

I bought vorshlag camber plates through a member here and installed the 350R springs on my car and went straight to 3° of camber. I'm not sure if it's better than stock since I took my car from stock everything to SV501's on cup 2's, R springs, on camber plates. I've only done about 8 Track days so far and the first time i took the car to Laguna Seca my buddy clocked me at 1:45. Thunderhill east with bypass was 2:07 via my AIM solo. These are the only metrics I can present given my lack of experience on the track to date.

That said - i'm thinking of dialing back the camber to 2° and seeing if that makes a difference at thunderhill. If there's anything to be said - right now i'm turning in very hard and the car just plants it's-self in the turns. I linked my thunderhill video if you want to see. Just note - the 2:07 lap is not in the footage and right after i did a 2:07 lap i pushed harder and went off-roading, haha.

Can you take tire temps at the track? Temps across the tire should give you a good indication of how much camber to run.
I had the dealer set front camber at 2.5 with the factory "R" camber plates. Its worked well for me so far.

last time I took tire temps it was within 10-15 degrees across the tire i believe.
32 PSI hot in all 4 tires.

That's good to hear. So far I haven't met another 350 owner running 3° which is why i was thinking of going down. I have the Vorshlag plates on my car.

I have considered going up in Camber. I depends upon the track. One I run on wears the fronts and another the back. I get good wear across the tire with the outside cording first with the center and inside not too far behind.

I'd be curious to see what you think when going up in Camber. Good to know - I haven't made it to the cords on any tires yet, but I can say i'm getting even treadwear across all tires right now. I'm running stock setup in the rear. I've been to laguna, Sonoma and thunderhill so far.

Are yiu putting cup 2’s on the apex’s?

if you have vorshlags, and without cutting the strut tower, the max i was getting was -2.5 camber. The car needed a lot more.

now im running -3.7 up front and -2.3 rear and wears perfect
