I remember a couple people talking about it awhile back, but I've never heard of anyone actually doing it...Would make some nice drag wheels and tires for someone.

great idea and all, but the only good tires i found that would fit, a 335/30/18, are michelin pilot sports, at $459 a pop, with a treadwear rating of 220! it would be cool, but i am not rich, and the price of our tires is already running me broke!

 

F1s are available in 315/40's (Ferrari application). Dunno the price.

I was considering widening my rears, but you lose the ability to rotate the tires.

And it could badly upset the front-rear balance. The truck already understeers. Putting more rubber on the rear would make it worse. I already run 5 PSIG less in the rears on the track to compensate.

 

I sent the seller a question on who did it and would like to see the backside.i have been wanting do this for awhile But was going to use 2 rims to make on[cut the back off of both and graght it to the one.That way I eliminate one weld which on a wheel is a bunch of heat.And the wheel comes from the factory heat treated.So that would cut down on the annealing of it.Sta

 

Tim,

You truck "understeers"......it pushes?


MIne has NEVER pushed or understeered unless the front tires were low. I have the other problem (and I like it) my truck is lose or oversteers!

Try a low-speed tight corner, at an autoX for instance, or the back hairpin (turn 7??) at TWS.

You'll get push on corner entry well past the apparent apex with light to off throttle. You can kick the back out with the gas, but it's slightly faster to go through at the limit of adhesion and a light right foot so you can put the power off with less slippage. At TWS in particular there's not enough room to set up a good drift and because the delay in getting traction back from snapping the rear end out is a greater penalty than taking it slow you just plow. it sucks, and does it even in the STi. (although lift-throttle does work better in that car). You're also limited because you can't get too throttle-happy since you're setting up for a more important left-hander that leads onto a straight.

 

Yes Nathan I can MAKE the L push, but it wants to oversteer much more than it wants to understeer!


Jerry

 

I can't see how that is possible. At the risk of lecturing you on things that you may already know, please let me explain why I say that.

First, just about every car known to mankind has left the factory understeering. Even Porsche 911s. They do this for safety reasons. Only an exceptionally talented driver can handle a neutral or oversteering vehicle. Sh*t just happens too fast when the car does not push.

My truck understeered stock. So did George Vye's (alphadoggie) stock L on race tires (I was riding shotgun at an SVTOA event). So did yours. It's just the nature of the beast.

Second, push is especially prominent in front-engined vehicles, and even more so in a truck, where the back end weighs nothing -- something like 57/43 weight distribution on a Lightning. So even an engineer can show how much and why a Lightning pushes.

My truck still understeered after I installed the Hotchkis full meal deal and QA1s. Irrespective of shock setting or tire pressure.

On the banked oval at California Speedway, as I went faster and faster through the turn 100 . . . 110 . . . 120 . . ., I had to crank the steering wheel more and more to keep the same line. Classic understeer. In an oversteering truck, I would likely have ended up against the retaining wall off of my right shoulder.

Same thing in a constant-radius sweeper at Willow Springs. With the steering wheel at a given setting, increasing the speed will cause the truck to slowly start pointing off of the track.

And it still understeers with Stan's 1100 lb springs, the DJM control arms, the 1" shackles, and the Hellwig rear mega-stabar. And every intermediate step along the way. Even with 5 lbs more air in the front, it pushes. Not much, and not as bad as stock, but still definitely pushing. And I like it that way. The alternative, at least for a driver of my skills, would be frightening at best.

Throttle-induced oversteer is another animal all together. Not surprising that a truck with 450 lbs ft has it. But that's not the same as f/r suspension balance.

Sorry for the lecture, Shadow, but I did not want to question your statement without explaining why.

 

I get understeer often autoxng a highly technical layout...

Stan -- WELDCRAFT was the shop that did BABolt's wheels....dunno if they're still around, their website is gone.

 

I'm not around the site much anymore guys but I'm the one selling the Rims and tires.. The L did look very tough with the wide rubber on it.

I posted some pictures of the inside of the rims for those who had questions

 

There's a place in MI that does widening. I checked a couple of months ago and they were open. I *think* it was called Weldcraft...

Also, didn't the Ranger variant of the Lightning featured a while ago have 11.5 inch rears? I wish FoMoCo would've done this with our trucks, or at least make it an option!

 

Tim,

Maybe I just don't understand. I agree with everything you said above. What I call understeer has only happened to me one time on track. I went into a slow right turn way to fast and when I turned the wheel the truck kept going strait. The only way I made it turn was to hit the brakes. I thought that's what understeer was. Now I drive differently. I brake in a strait line before the turn and then steer with the throttle. Hell you guy's know alot more than I do about all this stuff. Maybe I'm just not going fast enough into the turns to have this happen like it did to me the one time! All I know is I would not want the rear to be any more loose than it is. Maybe it's just my driving style. My first instructors did not like the way I drove and tried to change me. Now they have a national dirt track champion serving as my instructor and he is not trying to change me. In fact he likes my driving style. We have the rear end hanging out at over 110 mph in one of the turns at Motor Sport Ranch when running it clockwise. The turn is called Riccochet.

I guess I just don't understand.

I just emailed weldcraft since I couldn't ge tin touch with babolt.
I asked if they can do my 04 wheels in the rear to fit 325/335's, so 11" or 11.25" widening. like MNLightning's.

 

They are still around.
