I was looking through this site...

http://www.bryanf.com/510/index.htm

and found that for his rear he used tubs. From reading through the rest of his site he says that the car handles pretty well and he doesn't have issues. Is this due to the rear suspensions setup?

What would a street FB prepped to a similar level (completely stripped, rear done like this car) run into with a Ford 8.8 and a stock suspension setup (Watts Link and what-not)? I like the way he did this because it kept the body looking "right". Would an FB running similar tire/wheel size in the rear and front still be able to handle properly if set up with a shortened rear end and minitubs? I read Viking's threads but I haven't heard him say anything about street handling. Plus, his suspension setup is different.

OK, I understand what a Back Half-ed (SP?) car is. Tubbing, ladder bars, notching, full 4-link... etc.

It's a drag racing thing?

So then what about removing the rear floor pan... cutting or what have you and then tubbing without the ladder bars? Would this allow the rear suspension to function properly with a shortened rear end? I want big wheels/tires on the rear but I want stock body lines. Something like 12" rear, 8" front?

I mini tubed my Rx7 just for extra wheel tire clearance. Im fitting a 17x10 on stock fenders. I also dont really drag race much, so its mostly just for autox/road course for me

Hey, awesome response. Two questions...

1.) Do you have any pictures?

2.) How is it working out for you?

OK... more questions...

Did you take out the whole rear floor to reduce weight? Are you using the stock suspension set-up? Would you do it again if you started over?

Hmmm... I want to do this without doing anything to the frame rails. I guess what I should be asking is how much I can move the rear tubs in (minitubbing) without having to do anything else. What is the widest wheel/tire combo anyone is running in the back without relocating anything other than the tubs?

This is not for a drag car, I don't know if that's what is stopping our resident big dogs from replying or if they just haven't been on since I posted. I just want to keep the car's body stock but run some wider wheels in the back and save weight by removing all of the heavy stuff in the back. I'm not concerned with keeping anything mounted to the rear floor underneath the car. The underbody fuel tank will be replaced with a fuel cell and whatever else bolts up under there (not much if I remember correctly) will be moved as well.

Nobody else has done anything like this? What I'm really wondering is (and again, thanks for the reply, driftking! I'd still like to know how your setup is working out for you, although it's way different than what I'm planning to do suspension wise I'd love to hear about the process you went through with the tubs) if I tub/cut/hack will this affect my handling in a negative way compared to flares?

Why do you want so much tire in the back if you're not setting it up for drag? Really, beyond a certain point wider wheels will not help your performance. And looking to do such a drastic stagger in size between front/rear is going to open a big can of potential handling issues for you.

What are your goals for the car?

Goals for the car...

• Extremely light weight (I want around 2150 or so with driver, no interior, aluminum dash, cut out as much as I can, etc.)

• Very precise handling (I want ReSpeed R&P, Tokico Illuminas, Re-Speed front and rear "coil-overs", GSS Ford 8.8", full cage, etc.)

• Simplicity (I guess this ties in with the weight part)

• Decent power (~250 RWHP, I want S5 Turbo 2, BNR turbo, Microtech, etc. I believe this is acheivable)

I would think the rear wheels being at least 10" (and maybe not any more than that) would help a great deal with the handling. I understand the great difference between front/rear might cause problems. What problems could come of this was part of what I was asking. I've never driven a car with a 4" difference between front and rear wheel width so I don't really know what it feels like. 2" difference might be a better choice, yeah?

Is this what you are thinking of?

The huge difference between the front and rear rear tire width will make the car handle like crap for cornering/road racing. With that wide of a tire and the stock wheel to wheel width, understeer will be magnified even more over the stock deficiencies. Keep the rim/tire widths within 1-2" of each other. I'm running 9" front, 10" rear width rims which feels like a good balance.

If you are going for light weight, are you sure you want a Ford rear end?

I'm currently running the suspension you want, but I'm using 13x8 Revolution wheels and 215/50/13 tires. This is a very nice handling combination.

If you get up to 200+hp, then you may need wider wheels, but you could go to a 10 rear wheel without having to tub it (I'm pretty sure on this, but not positive).
