Just curious if anyone has ever thought of a way to possibly fabricate a way to fit wider tires on a 2g on the inside instead of having to run fender flares. Im sure it wouldn't be easy but i just think all the time how nice it would be to be able to fit a 255 or 265 tires without having them stick out of the body or rub the fenders. It seems to me if there was a way to fabricate a new set of knuckles to give more clearance would be the only way. Even just an inch MORE of clearance would open up so many more possibilities of wheel and tire setups!
 
You can modify your knuckles, ive done this for mine and Johns race cars, its not something to take lightly though as you need to reinforce it at the back, i got 10mm which is not 1" but its enough, i run a 255 and the fronts dont stick out but my rear does but thats on purpose and i used a spacer for a wider rear track also 255 tire.

May i ask WHY your wanting to run such a wide tire?
 
Basically i love the look of a meaty tire on a wheel such as a 17x9. I currently have 17x9's with 245/40 tires at a +40 offset. Id love to fit something like a 17x9 +40 with a 255/40 drag radial. Just that Bubbled tire look on a 9 inch wide wheel looks so good when you see it on cars that can fit something a little wider. Even just to gain 20mm or so from a redesigned knuckle would be awesome! @ec17pse
 
Re designing a knuckle is not that easy LOL, it takes alot of investment and research and time to build a knuckle for its job, im looking into billet knuckles but to be honest its a real slow back burner as its just alot of time and cost to do it but ive had scans and we look at it once in a while LOL.

I got a 36 offset and its pretty nicely tucked, the rears would be fine with a 5mm grind off the knuckle or even less then 5mm really, but the offset your wanting to run is alot more then you need, 34 would be fine and still stay tucked just about
 
Do you have any pictures of the reinforced knuckles?
This is all i have on my phone atm but the pics are on my main computer but its off as im in bed being many hours ahead of you guys,

These are johns set, as tagged above

Damn. I like that idea. How much clearance does he have with the lower compression arm on his car at full lock after clearancing the upright?

the modification is only to the knuckle and make it deeper, it will still turn as much as it would before as its not altered the turning side of things just the depth of the tire he can fit, so the compression arm is pretty good for super wide tires from stock
 
very nice looking. If those gain you 10mm of clearance, you should be able to fit a 255 tire at a +40 offset no problem
most certainly, it seems like it will be fine with a 40 offset with 10mm.

but as I said recently, I have a 255 ET36 on front and it sits flush with the fender! so as long as you get around that its all ok if you set on an ET 40 then yes you will need to have your knuckles modified
 
Good to hear the compression arm has enough clearance. It's been a while since I was under the car measuring that stuff and couldn't remember how much room there really was.

Do you think that ET36 would still clear a 265 tire on a 9.5" wheel? Or would the knuckle require modification to fit that? I was planning on a 9.5" wheel at ~ET35 for my next setup, but worried about rubbing the fender. Are your wheels 9" or 9.5" wide?

mine are 8.5" wide, a 265 i think is just possible on the fronts but it will be close if not touching, the rears however wont fit with enough clearance as mine where like 2mm but ive used a spacer anyway so not an issue there for me now,

fenders are difficult as depends on suspension aswell and springs, mine dont rub but ive got stiff springs and its rebound is set high, while my rears stick out the fronts dont but i dont get rubbing so your ride height will play a role in that aswell,

you can either adjust for your ride height and spring or adjust your suspension for the tires you want to run both require marking out and checking your setup
