Mini-Tubbing for cars under 500hp

[rogue]

I was thinking about this the other day. Why is it such a trend for so many cars running massive 335 rear tires? Wouldn't having a large tire in the rear and a 235/255 up front cause a detriment to handling?

Why the need for a 335 tires on a car only putting less than 500whp to the ground?

Besides cosmetically obviously. It looks badass. Just seems like an awful lot of work and money when a 275 will fit most peoples needs on a roadcourse.

My reasoning on this is that since my car needs shock tower repair,
needs the inner wheel house's replaced it seems like the right choice.
I will be in the minority having tubs and 200 series tires (thinking 285 40) right now

pretty much the same with me, I'm having to do a lot of body work and building an all new rearend anyway so why not. The difference for me looks to be somewhat around $1000 .

THE 69 camaro allways look good with a 275 ..BUT 335 is just so much more killer..I think they should have came like that back in 69:unibrow:

$1000?

Take into consideration the 10+ inch wheels, the 335 tires... That seems awfully low for a mini-tub.

I agree, Mule is sexy as all hell with that wicked stance. Theres some cars out there that definitely need all the rear tire they can get, Mule falls into that category for sure.

It doesn't get any sexier than this:

The LSX crowd seems to be doing most of the mini-tubbing around here, and most of their setups are less than 500whp, so is there some sort of handling benefit to having such a wide tire?

I was talking about the difference for me buying new rearend
replacing stock wheelhouses and buying wheels and tires that I have to do anyway. tubing a car if nothing has to be done is of course much more then a $1000 difference in parts.

How about forward bite???? You think 500 rwhp has a chance with a 275mm on the street?

[COYBILT]

I would say there useless unless the car is making over 600rwhp.

It is all in the suspension, but in these types of cars it is different. there not drag cars so there suspension design is not aimed at hooking up out of the hole.

Hell guys run 9s on a 9 inch tire but, that is a whole different type of car.

If your running low profile tires though and stiff coil overs your going to get no bit, so it might make sense to run a wide low profile setup for straight line and corners. This description I gave is sort of crude, but it gets the point across.

Most guys who minitub and run 335s are not running 235/255 up front. 95% I see run 275s in front, usually with an aftermarket sub.

And I don't see many 335 rear tire/minitubbed guys with less than 500rwhp.

my car is mini tubbed, and currently has around 440 horse and a set of 295. i plan on widening the wheels to 12 inches and running a 335 in the near future, along with some more hp.

and i mean in all honesty, if i wanted a balls out performance car and didn't care about aesthetics at all, i wouldn't spend my time and money on a first gen camaro. a C5 Z06 with the same amount of money invested would probably walk circles around even the most well balanced and setup pro touring camaro... but then it doesn't have the presence and look that a first gen has.

On alot of cars we've done, we narrow the rearend and leave stock tubs. Its a good compromise and gives the look we want without the major surgery. This is a car in our shop now with 275 and 245's.

[Flash68]

Actually, it depends on the aftermarket subframe and if it is a 1967-68 Camaro, my 67 has 335's, and I also have 255's in the front. I do have more than 500 hp, but I probably would still run 335's if I had less than 500 hp. I just like the look of it.

Is there an aftermarket sub that doesnt allow for a 275 front on any year 1st gen? I am not aware of one. I am one of the few who is running a 275 with the stock sub but most do not and many advise against it. I obviously give up some turning radius ability but it is what it is. I believe it is easier with the 67-68.

But I agree the 335 rear, regardless of need and power level, it just looks bad ass. :)

[XLexusTech]

The DSE subframe on 67-68's will only allow for 18 x 9" rim, so you are limited to a 255 size tire. DSE did try a 275, but it hits on the fender lip. While 69 fenders have more room to run the bigger tires. I have NOS front fenders, so I rather go with a smaller tire. So most likely with your 275's you will hit the fender lip, when you hit a bump.

There's some great info you don't get every day. Thanks for the heads up on that. Not that I was going for a DSE Sub for my 67 anyway but its god info none the less

The reason I'm mini-tubbing is honestly budget. It sounds weird to say, but the truth. I'm planning on running Vette wheels. Either take offs or reproductions. They're 10-11 inches in the rear and widely available at a very affordable price. You don't see many high volume production aftermarket wheels in widths greater than 8.5".
I rolled my own mini-tubs by widening a set of reproduction inners 2.75". I have to build a new rear anyway so I'm building it a little wider than stock to account for the high offset.

A second reason for it was the "while I'm at it" syndrome. I figured it would be much easier to mini-tub it now than to do it on the finished car. I'm only planning on running 295's out of the gate, but I'll have a ton of wiggle room and can always add more tire as needed.

That looks great! How much are you guys narrowing the rear per side?? I used to run 18x10's with 5.75" bs and it looked sweet as well. Yours looks to be a 10" wheel with about 4.5" bs or so??

I don't think the Chris Alston Chassis accommodates an oversized front tire either.

We narrowed a 9" 1.5" per side. and I believe it is a 4.375 B.S. on a 18x9. A 10" will work but we wanted more tire bulge. We also fabbed an inboard shock setup due to caliper clearance with this setup as well.

Thanks for the info!

I do believe it does..


In any event a 335 is all about looks.. a better combo for performance would be a 315/275 ... when there's too much of a size differential between the front and rear it just creates understeer.

But it does look sweet.

[ArisESQ]

I do believe it does..




i could be wrong, but off chris alston's site, this is the description for the clip;

7701
67-72 CAMARO/FIREBIRD/NOVA BILLET MOUNTS
Price $ 1789.00
Direct bolt-on-clip for '67-69 Camaro, Firebird, and '68-72 Nova. The frame is factory welded in our special fixture. It is laser cut, formed and welded out of 7 gauge steel. Front clip keeps the tire in the stock location, there is ample room for up to a 17"x8" front wheel with 4-3/4" back space and P225/45-17" tires. You will reuse the factory radiator core support and bolt it into the front clip. Your front bumper, radiator, and grille will bolt back in the original location with the weld-nuts fabricated into the frame. We manufacture the billet rack-&-pinion to match the suspension crossmember width. When you add the Street Machine front suspension package to the clip, this assures you will have perfect suspension geometry (unlike our competitors who only have "Mustang II" suspension crossmembers and tell you they will fit the Camaro, Firebird, and Nova). The engine is mounted in the stock location, with billet side mounts or motor plate and mid plates. The package includes welded frame with all suspension mounting points; mid-plate brackets; emergency brake cable mounts; hardware and fasteners; and 104-page photo-illustrated instruction guide. Billet motor mounts or motor plates; and bolt-in mid-plates; urethane or aluminum body bushing; clutch pivot shaft bracket; rubber inner fender splash guards, and bolt-in subframe connectors are optionally available. Shipped in a palletized box, by truck, freight collect.


have they released a newer clip??
