I have done a lot of searching on this and don't think i've found my exact answer so I decided to make a thread hopefully to find my answer and help anyone else looking for the same answer.

I am in search of a inexpensive drag radial setup for the woman's ecoboost automatic so she actually has traction at the track. On the stock all-seasons, 1st gear is absolutely useless.

Car Details:
2016 Ecoboost Fastback
Automatic Transmission
3.15 rear gear
Stock suspension
FRPP Tune and intake
Stock everything else

Option 1: My 16x10" CCW's with a 28x10 slick from my '04. Did NOT fit over the rear brakes. Not even close.

Option 2: OEM 17x8 99-04 GT wheels with 275/40/17 MT Radials. Stock tires are 235/50/18 which are 27.2" tall. The 275/40/17 would be 25.7" tall.

Stock ratios put me at max speed of 124.5 mph in 4th gear @ 6,000 rpm.
The 275's would put max speed at 117.6 mph @ 6,000 rpm.

This obviously gives me a gearing advantage using the smaller tire, but would these rims even fit? I know these were pretty sucked in when I had them on my '04.

Option 3: 17x10 +20 10th anniversary cobra reps. These are the ones I am most curious about because of the width. I believe these are 99-04 offset and I can grab them cheap. I would put a 315/35/17 MT on these and would have more traction than she needs and would give the gearing advantage as well being that they are smaller diameter like Option 2.

I think a 28" tire would end up hurting times since the car has a 3.15 rear gear. Am I correct on this assumption?

The only thing i've seen so far is a thread with a 17x9 '95 Cobra R reps with 28x10 slicks mounted. Hoping to get some answers here though.

Thank you,

I picked up a set of 17x10 Bullitt style wheels and some 315/35/17 Nitto Drag Radials local and ran them once. They stick out a bit with my 20mm spacers still on (tossed them on quick at the track and didnt want to waste time removing the spacers) but worked perfectly fine. Being a manual trans car Im gonna ditch the drag radials and look for some Hoosiers next.

Good to know that the 17x10's will fit. Think they would clear the suspension without the spacer?

What's odd about that is the bullitt style wheels would not clear my 03 cobra IRS, but the ccw's will. Things that make you go hmmm.

Yeah I dont see any issue clearing without the spacers, I was in a hurry to get them on at the track and get some times so I didnt remove them.

The 99-04 wheels fit great front and rear if you don't have the PP (Ecoboost). They don't weigh anything. I use a 275/40/17.
