A buddy of mine ran the BFG 's in a 305 with the roush suspension and it didnt rub. Keep in mind a 305/35/18 is just a tad shorter than the stock tires. I am also running 4.10's in mine. Its hell on gas but pulls like a Motha off the line.

 

Wouldn't it depend on how much sidewall you want out of your 305s if you are lowered? I would think so...

 

Is your fuel efficiency pretty much out the window with the 4.10s? I keep reading is not, but if you have 4.10s and a shorter diameter than stock, then you are making the ratio even taller, right?

 

It wouldn't make it taller, it would make it shorter.

That 305 tire has a 26.4" diameter while a stock tire has a 27.2" diameter. That would make a 4.10 gear act like a 4.22 gear.

 

You are right, I got the wrong "taller", I meant to say shorter!

 

i'm running the 295/45's on 18x9 Hot Wheels Sixty Eights, and the car is lowered with FRPP K springs with absolutely no rubbing, even with people in the back seat. really looks good with the fenderwell filled up...sorry i can't post pics from work, but i will try to get a few once i get home for you...

 

Brotha man, you don't know the half of it. I have a 3 1/2 car garage and still don't have any room. My car, her car, my motorcycle, her motorcycle, couple work benches, beer fridge, TV.... geesh. I need a 6 car garage!
Actually the 305s that I run are 28.81" tall.

But to answer your question, I threw an extra 250rwhp to it, put in 4.10 gears, and with the tire size difference they come out to 3.89s.

 

For the record, you CAN run 315s without any problems. I've even seen 335/30/18s without any modifications.

 

Sorry this is turning into a never ending thread... but what about 315/35/18s on an eibach pro-kit? Or will you have to go with a 30 series?

What are modifications you can do to pull out a slightly wider tire (other than rolling the wells).

 

I can address part of your question - there is no need to roll the fender lips because the factory already did it

 

Any pictures?

 

I've been inspired by MTAS's ride.Its been a hot topic due to the fact it looks awesome.Soooo.... I couldn't take it any longer and got the 18x10's DD(for the rear) Bullitts (AR TT M's) with a set of 555 E-Nittos.I already have a set of 18x9's so i'll be selling a pair of them.They'll be in just in time for the weekend.
I'm also installing a CS front fascia kit and (Ford )side scoops.It been a maddd mod summer here in the Rockies.

 

here's a few quick pics...

 

nice, and you have the 295s on 18x9s in the rear?

 

yup, with no problems at all. some will tell you the 295's are too big for a 9" wheel, but Nitto's run small, if they were BFG's, they wouldn't fit.

 

nice, looks like I have 2 new tires in my future.

 

of all the cool cars Ive seen on the road/on the web, MTAS's still is hands down the best looking in my eyes...I want a set just like his too

 

So, what size tires and rims are you putting on the front?

 

I already have a set of DD 18x9's.But I'll be running NITTO 555's 255/45/ZR18 up front and 295/45/ZR18's on the rear.I'll have an extra pair of DD 18x9's if anyone is interested.
Tires came in todayWheels should be here by Thursday.

 

Nevermind.
