What have you done to your Tacoma today? 1st Gen Edition

OMG!!!

 

I suggested using offset numbers in this situation because they were comparing different width rims. Backspacing numbers are dependent on rim width.

Backspacing of 4.5" on an 8" rim is not the same as 4.5" of backspacing on a 7" rim. Offset and backspacing are not measured from the same place on a rim.

This can all be quite confusing. This link does a pretty good job of explaning the difference between offset and backspacing and explains it a lot better than me.

 

Offset is the more confusing to me because it is based on the centerline.

Backspace seems more straightforward when worrying about the placement of the inboard bead. From your link:

4.5" BS is the same regardless of the width of the rim. You have 4.5" from the mounting side of the mounting flange to the inside edge of the rim (as it were bolted to the axle). Unless there is some curvature of space I'm not accounting for.

The offset of a 7" rim with 4.5" BS is different than the offset of a 8" rim with 4.5" backspace. That I do understand. This is due to the fact that the centerline is a different distance from the tire mount point.

Edit: and it goes the other way too. A 7" rim with 0mm offset doesn't have the same BS as an 8" rim with the same offset.

 

I guess it's time to replace MAF sensor and front 02 sensor. What brands has anyone had good/bad experience with?!?

 

Well see, you can explain bs better that me.

I have to point out that this discussion was based on comparing two rims with dissimilar widths, dissimilar bs and dissimilar offsets. To compare them using offset instead of bs allows for making a valid comparison of where the tread of the tire will end up for rubbing purposes because rubbing on the pinch weld is dependent on the center-line and width of the tire. If the only concern was rubbing on the UCA and frame, then the bs alone is enough.

 

Yes, agreed! I'm coming from the viewpoint of rubbing on the frame so I'm more concerned about BS. Looking at offset will be more applicable to the pinch weld since that is more in line with the centerline.

 

I'm having the same battle in my mind as I'm debating if an aftermarket set of wheels will make a 255/85/16 rub on the frame or on the fenders. See if you guys can help me out.

I have stock 7" wheels w/ 4.70" BACKSPACING and -1.25 offset. On these wheels the tires did not rub at all. But I want a different look so I'm looking at some level 8 ZX wheels. They are 8.5" wide, 4.5" backspace, and -.26 offset (almost 0)


As I understand it Offset = Centerline - BACKSPACING

I'm trying to figure out if the new wheels will push the tires out (away from the frame) a little more than stock wheels. Also trying to figure out if the new wheels would cause rubbing. I'm going off my knowledge that stock wheels and 255/85/16's don't cause rubbing

 

I'd recommend checking if your tires will fit. BFG recommends 6.5"-8" wide rims for the 255/85r16 KM2s.

The rims will push the tires 0.2" away from the frame. (you're going from a 4.7" BS to a 4.5" BS)

Not sure what rubbing you'll get on the pinch weld.

 

I called cooper the other day and they said I would be fine, just not to go any wider. Hopefully they are correct!

If the new wheels only move the tire out by .2" then I should be clear of the fender and frame.

 

Made a new tranny mount

 

The frame should be fine. The fender, I'm not sure on. The inside bead will be 0.2" farther from the frame but the outside bead will now be 1.7" out from the frame.

If you have already beat down the pinch weld, I would expect you'd be fine but estimating from the fact that I'm running an 8" wide rim with 4" BS and 285/75r16s.

 

Welded.

 

i would like to give you my money. but winch mount and no toyota cut out.

I like the slimmer design for this bumper compared to the last front bumper. any chance at a diy bumper?

 

The next model will have a winch mount. This is the Weight Saver 1000.
I can do no cutout, different light holes, things like that. A DIY kit would be easy enough, so I could do that too.

 

I like with the Toyota, but don't like those long cutouts in the middle

 

You have to have them to be able to put a receiver pin in for the winch. Sure they could be a little smaller but if you have gloves on for some reason or just big hands in general you would appreciate the size. They will blend in when it's black.

 

Looks very gewd

That looks awesome. I haven't been keeping up with the changes you made to the bumper but judging from how it looked when you first made it compared to how it looks now, it looks so much better. So did you cut it down? It does look slimmer and doesn't stick out so far past the body. Good job

 

I actually completely redesigned it. This is totally new; I didn't keep anything from the old design except the mounting points.

Thanks guys. I'm happy with it. I will be putting this one up for sale so I can build a similar bumper with a winch.
