Staggered or Squared Setup?

[Rob-17GT350]

Apex wheels?

Yep, SM-10. 19x11 +52. +25mm spacer on the front.

Anyone have an issue with the studs sticking out too far through the spacer and contacting the wheel? My APEX are +52 with 25mm spacer and when I just tried them, the wheel still needed about another 3-4mm to still flush. They're SM-10s.

Are you using bolt on spacers? We are all using extended studs with 25mm hubcentric spacers. I would not trust bolt on spacers for anything more than casual street driving.

Ah ha! Ok well that makes sense. My project for this week. Thanks!

Apex had their own spacers that I use or OP Mustang also has some.

Awesome. And the studs to use are the ARP 100-7732.

There are a couple of options. I'm actually running Ford studs from like an F250 or something. Can't remember exactly what the part number crosses over to.

Nobody can ever tell you what setup is best for YOU.

Maximum Motorsports sells them and says they are fine.

It's your car and your risk. Accept the risk you're comfortable with.

The track community at large gas seen far more failures and risk with the bolt on spacers compared to extended studs and hubcentric slip-on spacers.

can't stop user error or poor quality

I'm just offering the engineering-based opinion of a company who's been on the track a few times. They wouldn't sell them if they were prone to failure

They are "more prone" than slip on spacers as there are twice as many failure points. Neither Apex or OP Mustang offer them as they're both heavily focused on track performance. Places like Steeda, LMR, and Maximum Motorsports are in the business of selling as many parts to as many people as possible which is why they sell both slip on and bolt on. Do your research and you won't find any reasonable amount of people who would advise you to run bolt on spacers on track.

I've used them on plenty of street cars but would never be caught in a competitive environment using them. If you're fine with the risk and potential suspension and body damage if they were to fail, that's a personal decision. Trying to pretend they're the same as or better than slip on spacers with extended studs is just blatantly false though.

I understand the logic and I don't use them myself, but if you go to 16:48 in this video of AJ Hartman putting a splitter on his race car:, you'll see that bolt-on spacers don't seem to concern him:



They're pretty hard to miss:

Can stock GT350 rear reels be used on the front with spacers. I believe the stock reels are +62 offset.

There are always outliers, but in general, the preference is always for slip on vs bolt-on.
