M-2300-T brakes, will forgedstar cf5 19x10 wheels fit

[c9zx]

I want to put the M-2300-T (2013 gt-500 brakes) on my 2007 GT. I want to run 19x10 on a square, rotatable form. F&R wheels and tires the same). Does anyone run this set up or know if it will fit?
Thanks, Chuck

Yes, they will fit with the GT500 brakes on all four corners. I run a square setup with 19x10 ET42 CF5's and Kumho PS-91 285/35's

He's referring to the 6-piston '13-14 GT500 brakes.

Apex 19x11's on all 4 corners, with S550 15in prem package 6 Pistons Calipers on a 2010 GT. Tons of room.

rpm427sc, Will the tires be inside the fender and are the longer studs required?

 

[Pentalab]

I believe the CF-5's, even in 18" diam rims, will also fit the 13-14 GT-500 6 piston brakes. As noted, the CF-5's in 19" will fit the 6 piston brakes. The F14's in 18" won't clear the 6 piston brakes.

The 18" Apex EC 7 reportedly fits over those brakes. I use the 18x9.5 but with the 14" brembos, perfect fitment. Tires and wheels are pushed out as far as possible while remaining just inside fenders, and no special studs required.

I'm running 305's on a 11in wheel (a little wider then yours) and they fit inside the front fenders with a small amount of Neg Camber. ET52 Offset w. a 15mm spacer works for the front and allows them to be moved to the rear with no spacers, hence the extended studs.

What style / finish are these wheels from Apex? Are you using 3" studs? I see on Steeda's site that ARP studs come in both 3"..and also 2.5". What brand of open lugs ?

I have a 2010. so this caught my interest. Who makes the spacers shown in your pix above ? These look like the..real deal. Hubcentric..and only 5 holes. I would have thought that at least a 57mm et would be required on the rears. Have you got a pix of the front + rears with this 305/11" setup, like taken from the font and rear of the car? It would be much appreciated. Are you sure a 15mm spacer is all that is required for the front of a 2010. I did some rough calcs and thought a 25mm spacer would be required.

CJ Pony Parts has spacers like that from 1/8" - 1". They recommend extended length studs if you go 1/2" or greater

I recall getting just barely one diameter's worth of thread engagement on the OE wheel studs with shim spacers less than one-sixteenth of an inch thick. No way would I ever bless anything much thicker than that with OE wheel studs. Even 1/8" could put you on the wrong side of "marginal".

On my 2010, the oem front studs are longer than the rear studs. Even with a 3mm front spacer, I still have more thread engagement on the fronts... vs the rears ( and no rear spacers)... go figure. I could go to a 5mm front spacer, and then be the same as the rears. I have well in excess of one diameter of thread engagement on the rears, like 30% more. I replaced the oem nuts with the chrome ones from AM, that use the hex wrench on the inside..and are open ended. These chrome ones have way more threads vs oem acorn nuts.

But if a 10-15-20-25mm front spacer used, oem studs have to be replaced...with longer ones. I'd like to know how long the oem front studs actually are ? Steeda sells the arp longer studs in both a 2.5" and 3.0" format.

I just measured a couple of studs on the OE hubs from my '08 (it now has the FRPP/3" ARP setup). Looks like there's 1.5" of thread measured from the outer face of the hub flange and about 2.4" overall length of the stud measured from under the head (back side of the hub flange) to the very end (includes the unthreaded starter portion). The hub flange itself is a little under half an inch thick (probably 12 mm).


When I was still running the OE hubs & studs, I remember it being very close to ten full turns of the nut from just barely 'caught' to 'snug', and I lost half a turn from that when the 11" wide Forgestar wheels needed to be shimmed slightly (0.025" DIY spacers) to eliminate a minor tire sidewall to strut rub.

So are the ARP 3" studs, 3" using your above format for the oem (2.4") ?

 

[Norm Peterson]

I'm guessing it's the length from under the head to the tip, as that's the way most fasteners that are flat under the head are measured for length (as opposed to conical head contours that fit into countersunk holes). I never measured them, and I'd have to at least pull a wheel to do that now.

Whatever it is, there's a lot of turns required to snug up the open-end lug nuts. More than I've felt like counting, with plenty remaining for me to run the OE acorn nuts down against the open nuts for a measure of stud thread protection against corrosion. I've got one more track day coming up this year and I'll try to remember to take some measurements when I put the track wheels/tires on.

What brand of lug nuts are you using? I'm planning on switching to longer studs if I ever need to replace bearings.

They're the small-hex (17mm?) open-end nuts that should be shipped with any Forgestar F14 wheel. Got mine through Vorshlag.

Don't offhand know whose they are, though.

Studs are measured as Norm indicated, under the head to the tip. These are the ARP/FRPP studs for the S197 Mustang and measure at 3.315" front and 3.115" rear.

I've been using Gorilla open end race lug nuts measuring 3/4" across the hex. These fit nicely within the smaller lug openings found on many aftermarket wheels.
