Nice job guys I bet that was a blast! And now you finally have some time to rest...

Im curious, how much more work was it to fit those 315/30s over say a 285/30 or whatever you were running prior? Im evaluating my options and if I could squeeze a 315 it opens up some other avenues.

You can kind of see in the videos what they did to "squeeze" those tires in there.

If you don't turn the steering wheel, you might be able to fit something wider. Where these guys are with the Falken 315/30s, they are likely very limited in left/right turn radius from tire rubbing on transmission and possibly getting close to the crank pulley on the engine side.

You won't be able to run any brake ducting with their setup (unless they can speak for that?).

^^^ It all has to do w/the Wise Fab front / rear suspension

W/out those special hubs & control arms, no good way to fit that wide rubber

+1 on the breakdown to fit 315's.

The front control arms don't have adjustable caster or camber so I don't know how they make a difference.

In the rear, the trailing arm only pushes the tire forward or back. This helps with lowering as the wheel travels to the back and rubs on the bumper bolt. This is the same as a few of the other aftermarket offerings.

There is only one place to go in the front after you rub on the transmission (which you will do with 285s), that is outwards. Unless, you don't mind not turning as much. I believe this car likely does not have a very tight turning radius and a polished crank pulley and transmission.

So really, the Wisefab doesn't do a lot to help fit that extra rubber beyond what other commonly available parts do.

I follow RS motors & Andy on FB.

Contact them, because they already noted that was the reason they were able to fit the 315's

Have you seen the swoop to the rear trailing arms?

I imagine they said all sorts of things about one of their sponsor's parts.

The clearance to the suspension spring is closer than to my R/TErnie trailing arms. So, the big swoop doesn't do much unless you also offset the rear coilover (or run a short spring which will get you 6mm), cut the exhaust hanger on the passenger side and then, you are closer to the inside fender wall than to the trailing arm. This lines up with prior discussions I had with Eric, notably you will likely have to do something about the insides of the rear fender wall before you do anything with his trailing arm.

Is the coilover mount on the Wisefab rear LCA more inboard than the stock LCA?

Also, my point was more directed at the front where I stated that they likely can't turn the steering wheel too much.

Looking at the inside well of my rear fenders will definitely show that even a 285/295 will both rub a fender and inner fender well. And my fenders are pulled about 20mm all around. So either you have to start cutting inside, those tires run narrow (not likely), or fenders are even more heavily massaged than mine.

And as has been said about the front, The trans is definitely a limit for steering angle. Hard to move that guy. Though you can just steer less and its possibly fine on track. AX would not work though.

I rubbed 275s on the 6spd trans case, at or near full lock. Good news is the 5spd case seems to be more narrow. Giving about 1/2" more clearance.

*cough* Not a sponsor *cough*

maybe someone should tell them to sponsor these guys though

IMO, you have to do some not so pretty things to make 315's fit. Probably not worth the effort for the average Joe.

Snagged these photos from the One Lap RS FB page so everyone could see. 315's def not for the faint of heart...

I think the front, and max steering angle are the bigger deal. Not much you can do with the trans there...

Yeah, but you can buy wider front fenders (or space the stockers) to run lower offsets and not cut the car up. A rear wide body panel requires cutting on the car. Or not running a widebody with 315's requires cutting on the car...lol
