Tire size and suspension options for Roush supercharged GT.

[Startawar]

As the title says, I’ve narrowed down the rims I want to these. Now just trying to decide on tire size. I want performance but also a nice flush fitment. My car isn’t used for drag or track, and is just a spirited driving daily driver.

My 22 GT is currently running stock PP1 set up, with a Roush stage 2 supercharger from ford performance with P-zeros which suck. I’ll be upgrading to Michelin PS4s

What tire size do you guys recommend? I’m planning on doing staggered, and then at the same time looking to get some lowering springs. My old 2020 wasn’t equipped with magneride and I had the Steeda progressives which were nice, This car is equipped with magneride. Thanks for the help.

Mp4S dont come in good sizes for a 10/11 stagger.

Best you can do is a 285/35 front, 295/35 rear with the 4S. You want the 305/35 rear but they dont make that size in the 4S. They make a 305/30 but thats shorter than the 285/35 front and a /30 front is too small.

People run the MPSS instead, they still make that in the 305/35.

As for lowering springs you’re on your own.

Oh wait they are a 30 not a 35. Excuse my ignorance what’s the difference? And why do I need the 35 over the 30?

Ok yeah I just looked into it…thanks.

well damn that messes with my whole plan.

so are 315/30s not a viable option? Speaking tires is a whole other language to me.

Still too short. You need a /35 to pair with the front.

FWIW, if anybody is buying tires online Tire Rack is the best online vendor. Great customer service and prices.

They also sponsor clubs, etc etc.

Have you considered going with 20"s? Your tire options will greatly increase. I and many others use Steeda springs. Make sure to choose correct wheels and tires the first time or will get expensive to change your mind after the fact.

I can definitely look into 20s, I’m definitely not against it. And yeah I’ve been just extensively researching and asking questions on different sites trying to find the right answer for this exact reason. Want to get it right the first time haha.

I went with 255/40r19 in the front and 285/35r19 in the rear with Conti DWS06s and love the set up

 

[Startawar]

Ok after doing a little more research, and talking with someone who had a similar set up to what I want I think I’ve decided on.

325/30/19 in the rear and 285/35/19 up front.

opinions?

I'm running 275+305. Suspension is Ford Track shocks and struts with Steeda linear springs. I'm running Cup 2 tires.

I run the same thing, but with Continental extremes. They have great traction.

That should work fine, as they are very close in height, as long as wheels have the correct width and offset.

Great, I found someone pretty knowledgeable on Reddit who is running that set up and he loves it

Just trying to decide on springs now.

Debating the Steeda sport progressives, or eibach pro kit. With magenride.
