Op not to get your thread hijacked but, Any pics of this car from underneath showing the tire to inner fender clearance? Or any pics underneath showing clearance for that matter. I wanted to run a 5.5 bs but didn't want to chance it.

 

Basically any high end wheel

Bogart
Fikse
CCW
Forgeline

I was able to get all my wheels ordered down to .10 of an inch
to what I wanted. Sometimes even less than that.

Steve Burger from Burkhart Chassis

I have our Fab 9 narrowed 3" per side. Partial mini tub, QA1 rear springs, Wolfe adjustors, Strange brakes, 15x10 Alumistar with 5" BS, 29.5x10.50 ET Drag. I need to clearance the front a bit but it will fit.

===============================================
Steve is at 5" BS and with a partial mini tub.

You should be fine at 4.75 BS with your 275 tire

IMO, Its either roll your fender lips or go looking for room inward.
Looking for room inward is not as easy as everyone running 325's or 335's (wide tires) makes it out to be.
(I have done all the mods to run wide tires on 4+ fbdy's so not talking out of the blue sky when I say this)

Anycase, you can run spacers but why pay all that money for a high end deep dish wheel and then need to buy or use spacers.

You have to remember in order to leave room for the spacers
You also will give away 3/4" dish depth lip by running a 5.5" BS wheel Vs 4.75" BS wheel.

 

gotcha. i see Fikse, CCW and Forgelines on drag radial cars sporting 275/60/15s all the time!



Bogarts are sweet wheels that you rarely ever see on the drag strip and never see on street/strip cars. thats because they are the softest wheels made out there. not applicable for most and not worth it for those that wheelie or street/strip their car.

i dont think you have much experience with drag racing tires and combinations and maybe you should stick with what you know. research all you want on the intrawebs. it is no substitute for having the real thing (for years).

 

Ok, smart guy, riddle me this. Say I order a set of wheels with custom backspacing, throw my 275 drag radials on and roll the fender lip to give me just enough clearance to prevent shredding my tires. Then, 6 months down the road, I decide to put a 295 drag radial on it...or a 325...or the new 275 Pro...or a slick. If a 275 just barely clears the fender with the lip rolled then there is no way in hell a bigger (wider) tire will clear. So now what? Order a second, third or fourth set of rims? On my car I can run any tire I choose and put the outside edge of the wheel/tire right where I want it by "adjusting" the backspacing with spacers. It's almost like I've done this before.

 

Interesting thread 4 sure.

 

I don't know how old you are or how old you think I am.

I am well into my 40's and was drag racing late 60's muscle cars in Englishtown NJ and street racing in Fountain Ave Brooklyn NY way before some of the people on here were even born. So please save your personal jabs for were it needs to apply.

Our drag wheel of the day was Centerlines, talking solid dog dish here...old school and five star Welds...those are the two off the top of my head that I liked running. My personal drag wheel later on when they came out was Centerline Convo pros and yes they were slicks with skinnies up front the whole enchalada. I hated them...car was squirly like a ****, trick was not to let off quickly to upset the drag chassis but you know **** happens in racing were you can't always control things any case I hated that flying carpet feeling, nothing like what a TA should or could handle like.

Car was full drag mode:
lightweight fiberglass removable nose
bbc, aluminum rods, nitrous, fuel cell, drag suspension, bolted pinned slicks, usual low tire pressure
roll cage, t400 rmvb trans brake, spool 12 bolt rear 4.56,
ect. what ever else floats your boat

anyhow full blown drag car...no tags...running the good stuff with lead!
how I miss the sweet smell of that gas

I even raced bikes for a while
had an AMA road racing license the whole bit
So any case you can say I was around for some years.

Getting back to the subject.
Fella asks a pretty specific question:
I give him a pretty specific answer, not a what if scenario answer.
Nor did I tell him to roll his fenders, so not sure where you guys keep
coming up with that bit about me only being a guy that rents a roller tool

Here is his initial question
Running a narrowed rear 3" per side
10" Champion beadlock wheels
275/60R15 Tire with a 11.5 width section
He wants the tire as close to lip as possible

So I give him an answer.
An answer that IMO is correct.

He is not running a big wide *** tire like all the ones you two keep showing
and nor did he say that. Even if he did, I still would most likely have stayed with a 4.75" BS on a 10" wheel.


So again I ask you

How is the above physically possible?
Let's translate this and compare your wheels on a stock width rearend
So other people who are not in drag mode can follow along

You are basically saying that a wheel with an 8.5" backspace + what ever over hang is on your tire...from the looks of your pics, looks like close to 1" ...big *** drag tires with big *** bulging sidewalls off the wheel.

would fit on the back of a standard width rearend TA.

breakdown of the math
(5.5" bs + 3" for the shortened housing)

mind you as stated:
running no spacers
Loads of room

So basically anyone that is running a 7.75" backspace on a standard factory width rearend which is pretty much the given norm on our cars is a giving up 1.75" of cush to play with.

Very interesting.
Because on my TA and my brother's SS,
Firebirdmuscle's car (shown above)...there was no room.

Hell I would even venture to say that if you put the rim
on there with no tire mounted and no spacer it would rub on the inside of
what we call a chassis (the part to the left and right of the bumpstop area)

Just ask Firebirdmuscle to put his (4.5" bs rim) on and add another 1" off the back his rim would be rubbing off the frame with your 5.5"bs recommendation

Where is the loads of room?

If there was any room left back there to do that with out mini tubbing
trust me I would have found it.

My bumpstops are fully cut off
I did the BFH mod,
I have an adj panhard bar
I have custom Midwest Chassis Rearend
I have custom wheels that can be ordered in any incriment

So please let me know how you did it?
How were you able to pull out another 1.75" of space back there?

And save the personal attacks, assumptions and BS name calling, what not
I seriously want to know how you guys did it.

How were you able to pull out that kind of clearance running that deep of a wheel and still have loads of room?

 

Ok, I'm done.

 

You know where to look to find the answer. The other thread we are in. I posted pix. You make too many assumptions. Its 1" inboard. Not 1.75". That's it.
