Ordering wheels, last questions/help

[Nick.V70]

Right now I am running on my 70' Chevelle the following-

Front Suspension - Hotchkis 1" coils & 2" spindles
Rear Suspension - 3" coils

Front 20"x8.5" & 255/35r20
Rear 20"x10" & 275/40r20

Here is how the car sits:




I put a floor jack under it to lift the rear 1" to say it's 2" drop so I can have some "Rack" look to it. I like it better this way over the 20"s.





BIG Questions I need help with-

1. Is there a rubber isolator that sits on top of the rear coils and then sitting in the chassis pocket? (my car seems to sit lower in the rear than others I see)

2. What size tire are most running up front with a 20"? Mine are VERY tight, I haven't had a alignment and that will help but still thinking my front tire size if off/ to large?

3. Should I drop to a 19" front wheel so I can drop tire size for better clearance? I really like the 20"s front and back .


I am ordering my new wheels and tires so I want to make sure I am going the right direction. If anyone can help that would be great

You can buy urethane isolators for the pig tailed rear spring on your Chevelle, will raise it about 1/2" if you use one on each end of the spring. Energy suspension makes them.

As for wheel sizes, i like stagger in wheel and tire diameter. Your more then welcome to call me and discuss siaze ideas.

Thanks for the info Frank, so are you saying they are like that from factory or something I can add to fix my rear stance? Sorry I bought the car and it had coils cut down so I am going back and doing it the right way, well for the most part for now until I do a full suspension package. If anything I might just order 2" coils.

I kinda ended up on the wheels sooner than I thought after going to our local GoodGuys show over the weekend and my wife and I went by the Rushforth booth and really feel in love with a wheels style so I placed a order with Jason but I am trying to put my end thoughts on the wheel sizes before he puts my order in and it's too late to change. We walked away ordering 19x8"s front and 20x10's rear but now I am thinking of 20" all around like the car has now and trying to stuff a 20x11 in the rear like I have seen others say can be made to work. I am not stressing on the paint on the car because we are going to re-paint it so this is my time to do any fixes to "Make" things "Fit"

Frank I am sure you are a busy guy and last thing you need is to have time wrapped up over the phone but thank you for the option, really if anything being your background do you think I am asking for big trouble running 20x11's out back and staying on a 20x9 up front unless I hit the tire size perfect?

Jason and I discuss backspacing and sizing on his diect wheel orders all the time. Our tech service is for members, not for sales. Sales just happen to come. So your still welcome to call.

As for size, your going to spend cubic $$$ going up to 11" wide for very little gain and a lot of possible trouble. Were it me, I would do the 20 X 10 and 19 X 8.

Those isolators were on some cars from the factory, probably not yours. But they will riase it half inch using them.

Nice car Nick.
Good luck.

I just spec'd my wheels on the car now and they are 20x8.5 w/4.5"bs on the rear and I am sure the fronts are the same also. So if I go with a 20x10 5"bs I will bring the wheel out closer to the fender 1" doing the math.

Man I still have not started building my rear axle and almost thinking of going with a 12-bolt out of a 66-67 that is 5/8's shorter on either side of having a 9" built so I can run a smaller backspace for a deeper lip/face. I know we are talking minimal here but at this point every little bit will add up.

I like the lower ride height. I would leave the back low and lower the front just bit more if it does not wreck the geometry.

I have a extra set of isolators. Pm me your info and I will send them out

The 5/8" will help and will give you 5/8 more lip, just that simple. If you build a rear you can narrow up to 1 1/4" per side depending on what brakes you run.
