Looks good!
What is your new offset on these wheels?

Somewhere around a 18x10.5 +55, and then add a 15 mm spacer making it +40

NiiiiiiiiiiiCE!!!!


What kind of suspension are you running? Dont you think 315 is a little over kill? Maybe 305, there is a wide body supra here with bolt ons that has 315's, I think its ok for him since his body needs it, but the Z doesnt need 315's imo, 305 at the most. But anyways, nice car!

That is an ongoing debate between JETPILOT and drumma, basically JETPILOT said drumma's offsets were whack even though they fit. Granted, with a fair amount of negative camber.

JETPILOT continued to post in other threads that things like 19x10.5 +11 won't fit on a Z, PERIOD.

drumma countered by saying JET was wrong.

JET countered by posting pics of drumma's car, showing his extreme camber and basically said that "that looks like a mexican lowrider Z" or something.

etc.etc.etc.etc.etc.

It is basically a childlike argument...

PS The above occurred in no particular order.

Also did they keep the heat affected area to a minimum while welding and did they heat treat the welded area afterwards.

There are many things to take into account when welding and specially a load bearing part, just think of a weld letting go at 100 MPH

Not picking on you just making some points I think are valid if doing something like this.
Pure paranoia...the welds won't let go because there is little / no shear stress across the welds when the wheels are turning. And the welds are no more likely to let go at 10mph than at 100mph. The wheel is turned from the center, which means the welds turn with the outer lip and everything else. Any damage that occurs to the rim will be of the typical type, a bend at the lip or a crack at one of the spokes. Since the rims are of quality, hopefully it would be a bend rather than a crack...

Could be paranoia and over analizing, hazards of being an engineer but the wheel will also see stress radially from the road and bumps plus the possibility of voids in the weld. Chances of something happening might be low.

Im running stock suspension. I just bought the Z in August. 295 is over kill. It just looks mean with fat rubber under it.

That looks much much much better than stcok. I wanted to do this, but I had no idea it was even possible. Thankyou for being a guinea pig of sorts...

+1. Great job on trying something different, but I have to agree with the above, since I am an engineer also. Heat treated areas, different stresses exibited (shear, compression, etc.). Too many factors. Also, yes the welds do feel shear stress. When you rotate radially, the tire contact patch is throughout the width of the wheel and hence puts shear stress on the welds when you accelerate.

So can someone knowledgeable about offsets guide me? I really really like this idea, so I want to take the rear track wheels that are 8.5 and stick them in the front, then take the fronts that are 8 and make them 10.5, the end goal is to have 255F and 305R tires. Will a 10.5 rim hold 305's? And will I just need spacers in the rear or will putting the stock rear tires in the front require any modifications? And what size spacers do I want for this? Thanks.

Very cool.

How much weight was added per wheel?

The rear wheels will fit fine in the front. 305 will fit on 10.5" wheel. I used a 15mm spacer for the rear.

I'm not sure. I didn't weigh them. It can't be that much. I just had a 2" band welded to them. I don't think even a half a pound.

Thanks. One more question... how much per wheel? And is price dependent on how much is added?

It was $175 per wheel. Give them a call. I'm not sure if it will be more.
