Connections.... Want to bring your hot rod up here?

I'm in for that lunch meetup.

I'm in for that lunch meetup.

There would be tire smoke required

 

[BCGPER]

I wouldn’t be opposed to hauling it up there, but I couldn’t partake in the smoke show. It’ll be in pieces to paint.

Spent an bunch of $ on base and clear (color committed now)

Can confirm.

Just posting some reference pictures here for "problem" areas on my car



A pillar trim



Cowl area from a "survivor" car (17k miles)

Cool radiator upgrade for Buick Skylark

Huge milestone. Jambs are done. Clear glosses.

Topcoat!!!! Let's go!!!! (Be a couple Saturdays before I can do that unless we get a CALM day like this again)

 

[mbryson]

Clear glosses sort of.... I might have to put 5-6 coats on this dog in case I have to wet sand the clear? I think as the solvent comes off the flow is interrupted? I'm a little concerned to spray this dawg now :/

 

[JeeperG]

Good luck

 

[mbryson]

Spent a LOT of time on this today.

That's a neat looking dish rack! 😉 I definitely wouldn't have had the patience to get it all straight and painted that nice.

Current rear tires



Vision Nitro will be ordered soon.

Got new BFG for the car. Rear wheels with their screw holes won't hold air with the BFG bead.


Weld ProStar are kewl but ouch on the price

Someone here likely knows what I need? Longstanding Skylark internet lore is that one can fit a 10" wheel and 295 50 15 tire in the rear tubs with 5.5-5.75" backspace.

How does that equate to -25, 0, +25 mm ? 25mm is pretty much an inch. On the 10" wheel, I assume 0 would be at 5"? +25 would be at 6"(ish)

WHAT IS WHEEL OFFSET?​

(Lea en español)

The offset of a wheel is the distance from its hub mounting surface to the centerline of the wheel. The offset can be one of three types (measured in millimeters).*
"The offset of a wheel is the distance from its hub mounting surface to the centerline of the wheel."

Zero Offset​

The hub mounting surface is even with the centerline of the wheel.

Positive​

The hub mounting surface is located in the front half of the wheel closer to the wheel face. This tucks the entire wheel in toward the brakes and vehicle suspension. Positive offset wheels are generally found on front-wheel drive cars and newer rear-wheel drive cars.

Negative​

The hub mounting surface is located in the back half of the wheel closer to the back lip flange. This moves the wheel out away from the vehicle brakes and suspension. "Deep dish" wheels and wheels for lifted trucks are typically a negative offset.
If the offset of the wheel is not correct for the car, the handling can be adversely affected. Often, when changing the width of the wheel, the offset will also need to change to maintain proper clearances inside the wheel well. If the offset were to stay the same while you added width, the additional width would be split evenly between the inside and outside. For most cars, this won't work correctly. We test fit thousands of different vehicle and wheel size combinations to confirm which ones work correctly. Our extensive database allows our sales staff to offer you the perfect fit for your vehicle.
*Backspacing, similar to offset, is the distance from the hub mounting surface to the inside lip of the wheel (measured in inches).


Another calculator that makes a little more sense to me

Wheel Offset Calculator

Use our wheel offset calculator to visualize the new tire position when changing wheel and tire sizes. Convert wheel offset and backspacing to calculate the correct setup for your vehicle.

I have a set of 295-55-15 drag radial’s on some Crager 8” wheels that you could put under the car and make some difference calculations from.

Awesome calculator

I do have a crude spreadsheet that I made years ago that calculates inside tire clearance and overall width from entries made about the car, tires and wheels. I have used it on a lot of cars with pretty good sucess if you want to give it a try.

I'd love to take a look at that spreadsheet. Re: your slicks, are the on 5 on 4.75 wheels? I running the 5 on 4.5" on the rear

The wheels are unilug, 4 1/2 and 4 3/4. Do you have 1/2 or 7/16 studs? I will try a PM to send the spreadsheet.

My brother has one of those cheap wheel and tire simulator tools you can probably borrow if ya need to, it's not perfect but it helped us enough to figure out the farm truck stuff.

Do you know what brand of tire simulator it is? I have been wanting to go with a 9.5 on the rear of the El Camino but not what kind of offset it will require.

Not sure the brand, looks like this. Just plastic with a solid core piece of wire.
