Has anybody minitubbed a thirdgen? I am planning on mini-tubbing the rear of my 87 to fit a 335/30/zr18 tire and want to know what is the best way of going about it. I want to use a 4-link and don't mind cutting into the floor pan as I currently run a 10-point cage and don't have rear seats anyway! I don't want to have to completly back have it with custom frame rails. I want to know if I can get away with installing the crossmember for the 4-link, notching the floor to provide clearence and cutting out the factory wheel wells and fabricating larger ones to tuck the rear wheels? Anybody done it or have any opinions about it?

if you are going to use a 4 link setup, you are probably going to have to backhalf the car.

Wolfe Race Craft sells a mini tub kit for 4th gen cars, it would be a real close fit in a third gen, the rest of the suspension mods are on you

I have read his thread on his back-half project, but I was looking to do something slightly more "stock" appearing. As I said befor, I don't mind cutting into the floor to install the 4-link, but I wanted to try and stay away from having to use custom framerails like the one's in his thread. I have done back halves before, just nothing without using the fabricated fram rails.

A "mini tub" is moving the inner fender towards the factory frame rails to allow wider tires. On a unibody car such as a third gen, there is no such thing.

Take the tires off and look inside the wheel well. Except for the raised area around the spring pocket which can be cut out and plated over to allow a little more room, what you see as the inner fender is also the frame rail. You can't go inwards any more than that. The best you can do is to modify the front of the inner fender so it's more square than rounded to allow a taller, wider tire.

The space between the inner and outer fender is all the room you have to work with unless you do a complete back half and install new frame rails.

You're not going to get a 4-link under the factory floor.

This is the best you can to to install bigger tires.

With those mods shown above, how big of a tire could you fit? What If I modified the inner frame rails and moved them inward? I could fabricate new frame rails that would run along were the factory frame rails run just inboard to give the needed clearence. I could then fabricate a new crossmember for the coil-overs to mount to move them inboard as well. I am not affraid to back-half it, I just wanted it to have a more stock appearing look. If I moved them inboard but followed the factory lines, do you think I would still be able to build a custom floor pan/trunk pan that to the untrained eye could pass as factory. I am trying to make it as clean of job as possible.

Few diff ways you could go. Stock frame rails in this one.. Well they were not anymore as you can see..

I dont know if a 335 would fit w/o going into the frame rail a little (notching it)

That cas has been replaced and im doing another mini tub now.
Coil over 9inch, etc..

Well, I guess what I'm going to do then is custom fab new boxed rear frame rails that are moved inboard to give the clearence I need. I will mount a upper crossmember for the new shock mounts and tie in a lower crossmember between the subframe connectors to provide a mount for the 4-link. I will then build a new floor/trunk pan with notches to clear the 4-link, and to clear the rear shock mounts. I think I will build new wheel wells close to the factory shape that will be just deep enough to run a 335 tire. The tire height won't be an issue as the od is only 26", so it just be a matter of making the wells deeper. I am going to try to make it as clean an install as possible as I do want it to look like it should have came from the factory that way. Then I need to try and figure out how to cover it all with the factory interior panels. I am going to start on this project in about a week. I will take pics every step of the way and keep you all updated! Are there any flaws or issues I'm going to run into that you jump out at you guys?

More pic's of other cars.with mini tubbs/tubbs what ever you want to call them.
not back halved.

How wide of rear tires are those car's running? I love the stance of that white car. And the pic in the middle looks as clean as ever, exactly what I'm shooting for! Do you know what size of tires those guys are running?

Wow, that car is absolutly beautiful! But, not trying to be critical, those don't look like 345 tires? I've seen lot's of pics of car with 335's (not third gen's mind you) and they are way wider than that.

That is by far the nicest thirdgen i have ever seen and exactly what i want to build. A car with big 18inch wheels that are WIDE and yet a clean look to it. And twin turbo'd with HUGE hp numbers. The whole car is complete. That car is amazing.

9secz28

Ok, I just looked at the WHOLE thread! Ya those tires he's puting on are definitly 345's! That car is sick!

come on don't make me drive over and look at how yours gotta look right now.
Prob not as bad as mine but Im bet its getting there !!

Never. It's clean for the little space that it is. Come on over and get this wreck out of the garage and I'd have all kinds of clean space.
