Bridging the fender gap...wrong way?

[Sinful_5.0]

Hey guys,

On my 2014 GT I have Steeda Sports + Koni STR.Ts and there's always been about a 3/4-1" difference in gap between the front & rear (rear having the larger gap). Now that I've added some addiitonal weight on the front with the Roush TVS, that gap is even more pronounced and when I do wheels and tires, I'm wondering if I can play around with sizing to bridge some of that gap...just not sure the consequences or if this is the right way to go about it:

Right now I'm liking the Forgestar CF5V and thinking of this tire combo:

Front: 275/35/19 Nitto NT05 = 26.65 overall diameter
Rear: 305/35/19 Nitto NT05R = 27.44 overall diameter

Basically, I'm just trying to decrease sidewall in the front while increasing it in the rear. In theory, I should gain almost an inch here.

Should I be okay with this setup? I remember reading some threads about if too great of a difference, it may throw off the advancetrac system...

You will be losing ground clearance as well if you go to a shorter front tire.

Keep in mind you are talking about diameter. The wheel gap in the rear will only be affected by the change in radius. Adding a 1" taller tire will close your fender gap by 0.5".

Why not install lowering springs that will make your car more "level" instead?

I knew it wouldn't be that easy. Good points guys.

Can anyone recommend some springs? I don't want to be "slammed" hence the steeda sports... But the gap differences are a bit much...

Bmr sp009

Yes, get the BMR SP009 springs.

I am currently running a 255/40-19 and 275/40-19 setup on my car with these. I don't have a picture to post at the moments as I am still editing a fresh batch from last night, but I will post one later.

Also, I would recommend running a 285/35 on the front if you have a 9.5" or larger width wheel. If you are running a 9", I would leave the 255/40 on the front for clearance purposes.

Here is a pic of my car on BMR springs. I thought it would be level, but didn't turn out that way for me.

The BMR springs leave you around a 1/4" rake after the springs have settled. I like that, though, as a muscle car should have a rake to it's stance.

Meh, no rake crew checking in here. Thats why I went with coilovers. I have a tiny bit of rake but I really cant lower my rear end anymore.

OP just put some sportlines on the car and call it a day.

funny you mentioned that.... I plan to run a 275/35r20 up front in a NT05 and a 315/35R20 NT05r when I pick up some forgestars next month. I was looking at pics of cars that ran a 275/40r20 to match the rear height and it looked dubbed out....but the 275/35 and 315/35 look pretty good together.

315/35r20 NT05r are 28.74 OD
275/35r20 NTO5 are 27.56 OD

I also plan to run it with the adjustable eibach coilovers so I can set the stance with them.

What sizes are you planning to go with on the CF5V's? I will do my best to point you in the right direction. This is all I do ALL day is calculate the wheel/tire setups for these cars :-D

But like others have already said, lowering is going to be the other piece of the pie. My suggestion is to always get your wheels/tires installed first and then judge your available space. With an aggressive setup, it is very easy to over estimate the drop and end up with rubbing.

This is probably our #1 most popular setup. The CF5V is only available in 19" but this is exactly what I recommend with F: 20x9 or 20x9.5 or 20x10 / R: 20x11 setups.

You can always PM or email me if you have specific questions.

Nice wheel selection on your site :rockon:

 

[blackbeast12]

Whiteline watts link has a ride height adjustment built into it for up an inch lower! How do i know? I got 1!

car looks great tho i myself am riding on sportlines

Thank you!

To the OP,

Below is a picture of my car on BMR SP009 springs. My rear tire is a 275/40/19 measureing 27.7" OD, front are 255/40/19 measuring 27.0" OD. The gap between the tires and wheel well should give you an idea of how yours will possibly look, but maybe a tad lower to the ground due to the shorter tires.
