Big Wheels Under Flared Lx

The car will have the A9X flares on the back, so just wondering what size rubber we can fit under there without worrying about tyres scrubbing and as we haven't had the diff made yet, would it be better to keep it standard length or get it made shorter.
From most of the threads I have read I assume it's safe to run 17x8's with 225's on the front without much drama. Can I fit a 17x10in rim under the back and whats size tyre can I run, Are 295's possible if minitubbed .
Cheers

But a 17X10 should fit ok, but as moot said.. it might be hard to get a good ride with them...
I have 15x10's on the back of mine, and i think a 295 would fit pretty easy (Just have a 265 on at the moment)

For example with those 15 x 10" US Indy Racers I had you could not fit anything larger than a 265 on the rim without it badly rubbing on the lip of the A9X flare -unless you jacked the rear of the car up to some rediculous height.
But with the 15 x 10" Challenger rims I now have, running more +ve and less -ve offset will take 295's easily.
My car is not tubbed.
Hope this helps.

Might be worth checking tire availability before getting too carried away.
295 is not a very common 17" tire size - infact I can't think of anyone who makes road tires in that size.
285 and 315's are far more common in 17".
285's come in 40 profile which have a very large rolling diameter and 315's come in 35 profile so they are wider and a little smaller in rolling diameter.
Both sizes will be a challenge to get to fit if you want absolutely no scrubbing in the rear with a couple of fat bums in the back seat.
Some people will tell you they have achieved it but they normally put up with some scrubbing and claim they have achieved a 'fit' anyway.
Mine is fine with the 285's with 3 people in the car but put a second person in the back and it will scuff when you are going around a corner and hit a bump.
If your diff has rubber bushes and no sideways location you will probably struggle more as they tend to wander side to side about 10mm.
The wider A9X flares are a bit misleading with large diameter wheels because it is the bit close to where the flare meets the body that becomes the main problem.
There is a bit of flexibility on how high you mount the flare on the body. I recommend you do it as high as you can without it looking wierd at the bottom of the flare where it meets the sill. You then need to be fairly brutal with how you cut the original wheel arch - I reckon you need to trim it back so far that the inner support (looking from inside the hatch area) which has a 90 degree flange spot welded to the tub also needs to be trimmed back and rewelded through the mid section to give more room. (I wish I did that on mine)
Mini tubs will help make it all fit a bit better but if you move too far inboard with the wheel offset it looks a little strange I reckon. They probably won't help as much as you would like either because the bit where the wheel is close at the back can be taken about 12mm in so it is flush with the chassis rail but then it is the rail which is in the way.
The chassis rail angles out through this rear section so the larger the diameter wheel, the less width you have to the chassis rail. You will no doubt have to move the shock absorber as well as they are fairly close too. I havn't poked my fingers in there for a while so I can't remember exactly how close.
You may also want to consider putting taller bumpstops on the diff housing like the A9X has but it still shouldn't be riding on these in normal driving with people in the back obviously.
I can take a few pics if you want to see what I mean above.

I have to send the forms off to transport either today or tomorrow and need to know what the new wheel track will be with the 17's. Does anyone have any measurements between the centers of each wheels, front and back, when running 17's. Are the wheel tracks on the sedans and hatches the same?
Toranamat69 - Thanks mate, a few pics would be much appreciated. Your setup looks pretty sweet to me, what size rims and tyres are you using on the front?

They really should be on a 9" rim with the 255's but that's life.
They are a really tight fit to clear everywhere and really need to be a fraction wider offset on the front.
This is the widest front track my engineer would let me have with the standard Torana front suspension.
I am in the process of taking him on with my new front setup as the track will be another 30 to 40mm wider but using these same offset wheels. It is looking good and this will solve about 3 different issues which I have with my front end at the moment.
Sorry I havn't taken any pics yet - my little bro is down visiting at the moment so we have been running amuck.
