Fitting 16x8 Cobra Rs on an S197

[GeorgeInNePa]

I am looking to use 16x8 replica Cobra R wheels on my 2011 GT. Is there anything special needed to make them work?

5x114.3 bolt circle and 5.1" back space.

They won't clear the front will they? I know stock v6 wheel won't.

Probably not.

I want them just for the back for drag radials. I can get two 295/50/16s for the price of one and the wheels are $100 each.

Oh ok, I was hoping you didnt want to run 16" cobras on your car all the time..talk about ugly! They will work fine for just something to mount dr's on. Won't have to worry with grinding calipers and repositioning the rear sway bar to run 15 inchers.

That's ehat I wanted to hear.



Mainly because I went and bought them.

They're at a friends place in MD. I get to pick them up this Saturday and try them out.

Post up a pic when you get them mounted on the car.

I need to buy some new ET streets..did you buy the tires seperate or was it a deal?

I bought the tires from a friend and had the wheels shipped to him. He got them mounted.

The price for these tires is just about the same as the 295/55/15 MT Street Radials. The sizes are close 27.7" vs 27.8", etc. You just lose a little sidewall.

That setup is going to do very well for you especially with the Circle D

I wonder if there is a difference in compound between the two? The tread pattern is different b/w the ET Radial and ET Radial 2 to make the ET2 more rain friendly. I think the 16 has plenty of sidewall though, but I can assure you that the 295/15 hooks!

How tall are those?

I'm going to try them out on Saturday with just the Tune.

They are both listed on MT's site as R2 compound.

How tall are those?

27.7" tall, 87" circumference.

I think the OEM 19" tires are right around 27.7", aren't they?

 

[GeorgeInNePa]

Well, they stick out.

The wheels are a 5.1" back space. The Racestar website claims the 15x8 wheel has a 5.5" back space. I guess that .4" makes a big difference.

Now, don't get me wrong, they do work...

I am not getting any rub, because I'm at stock height and just a tune. So I don't get enough squat to get the lip anywhere near the tire.

I've got them for sale on Modular, they should fit a 94-04 just fine.

 

[SlowA$$5.0]

They stick out a little more than my 15x8 race stars, but not .4 inches more. At least you don't have to deal with the stupid ring, oval shaped lugs, and offset washers.

Really? Hmmmm.

Maybe I should just keep them.

I thought the Racestars were tucked in, under the sheetmetal.

The 15x10's do. It's dark now, but I took a couple of pics to show how they stick out.

 

[GeorgeInNePa]

You're right, that is close.

 

[GeorgeInNePa]

I need to mount the drag wheels back on there and take some measurements to the inside. This might help:

The wheels I have now have a +15mm offset, so if I went with a +38mm offset that should move them inwards 23mm (almost an inch). Correct?


ETA:
Or stop worrying about it and just run these for a while... LOL

 

[keeno]

Yeah, if they dont rub, just run those. They are only for the track anyway right?
Those cobra wheels are made for sn95 offset, so you should have guessed they would stick out. I just bought a pair of 17x9 cobra r's. Waiting on dr's now. I'm sure they will stick out on my 05, but I'm gonna use them on my 94 also. They will tuck in on the 94.

I have 23 runs on them now, three trips to the track. Plus about 550ish street/highway miles. I drive them to and from the track.

With the stock suspension they are fine, especially with an automatic.

I plan on Weld RT-S rims, big and littles, but these work for now.
