Those look like what Bill Guzman has on his Orange roadster.. Except I think he has 15".

Those do look good. Too bad they don't make them in a 5-120mm 17" size. My problem is compounded by needing approximately a 42mm (40-46) rear offset and a 13mm or less front offset.

I just checked Discount Tires, and much to my surprise (shouldn't have been though) I learned that a 4-3/4" BC is actually 120.65mm which is a little over .025" and definitely enough to affect the fit. RATS! Wonder whether the Jag pattern is 120mm or 4-3/4" (120.65mm)?  They could be bolted up, but it would cause the studs to splay slightly.

Calvin,

Be carefull with those RPF1 in that size. The 7" will not have the same profile as the ones pictured! That one is likely the 17x9" which looks great with the spokes sunken in.

Jim, You could always change the Jag rear to Ford 5X4.5(same as lots of Nissan,Toyota,Mazda,Mitsubishi,etc.).Daze Jag IRS part 3 about halfway down shows how.  http://dazed.home.bresnan.net/JaguarIRS3.html

As I'm not in a position to, nor have the talent, to flare my fenders, what is the widest tire and wheel offset combination I can use?

Carl is going to try 15X7, 34-40 +offset wheels. probably 225 or 235 50 tires. I think he will lose the bump stop hump in rear wheel well and hasn't measured the front yet. Probably  have to pound in the factory dent in front wheel well also. He has rolled the fender lips in allready and uses a panhard rod. My guess he will have to roll a baseball bat around the tires to prevent rubbing. Carl, tell me if I missed anything.

Here you go Jim,

Paul, Lots of guys have fitted 195-60-15 on 15X6 MGB offset(26mm+ I think). Still have to have rear axle centered. Flared fender guys usually use 225-50-15 on 15X7 0 offset or 15X8 MGB offset to fill the fenders. Some use 16 or 17 wheels also, then you would have to go 40 or 45 series tires for the right overall diameter(usually 23-25 inches). With all of these combos, I would roll the fender lips and use a panhard rod.

Here is another thought. Maybe you can just have rims made to your spec?

I know of two MGBs running 225/50-15s without flares. Tight fit. Nine inches of rubber is very close to max for the stock wheel well.

My plan is 235/45 or 225/50 (same overall width).

Jim,

I found SpinWerks Racing Wheels to be very acceptable on my former SCCA F Production MGB GT.

And I am now using the 15 X 7 - 11 lb. - SpinWerks on my SCCA GT2 RV 8.  They hold up to the grip of Goodyear Racing slicks, but require huge fender flares at all 4 corners.

keep them on the track

Their 17 x 10 is 18.3lbs. and about $600. Not exactly a lightweight, but thanks.

Finally found some weights for the Drag DR-44, 16.7 lbs. Ouch.

May have to stick with my 13 lb. 14s awhile longer.

Carl, How about the DR9 in the chart. 15X6.5, 38mm offset and 13.2lbs. Available gold with machined rim.

Have you looked into companies like Billet specialties? Than can make just about any offset and bolt pattern. Lots of 17" choices as well. I am just not sure of the weights. Price will depend on the wheel you choose.
