Mind numb about suspensions

Hi guy's
I'm doing the investigative work on how I want to proceed with my 1989 vintage Paul Bennett Cobra. Not a hole drilled in her yet, Anyone got one? No not a hole, a Bennett.
I've got an 84 jag XJS rear with the required shortened axials and arms that is going in.
I am looking at the Fast cars IFS instead of putting my MG suspension in.
Here is my question: I have not done the math or called them due to mind numbness.
Fast cars makes a 2 inch wider version of there IFS unit. would there be an advantage to this wider version on my car?

I know this is kind of an "own opinion" kind of thing, but the Fast cars IFS seams to be the best bolt in kind of option out there. Ya the 3,850 + is a lot but the outcome is what I am most concerned with, but the investment dollar of having it when and if I ever sell it would also be there.
Opinions and comments please.
Thanks Shelby Dave

A little more investigation of my Bennett info yielded a 56 rear track width and a 54 front with the MG suspension. The car would be squared up with the 56 wide track of the Fast cars IFS. I could run all 4 the same size tires (wheel wells permitting) and the car would have a desirable square track.
I like it.
Any opinions or advice on the Bennett car?

No opinion on the Bennet car.

Hopefully you've already run across and read this thread (Fast Cars IFS), which deals with the Fast Cars IFS, enlarging mounting holes before attempting to install it, etc. The thread does deal specifically with using the 2" wider version for Cobras, indicating the narrower version is really intended as an MGB replacement, while the wider version is for Cobras.

wow thats hard to stop watching. That counts.

Thanks Brian I had not seen that thread. It was very helpful and gave me a good feeling about my decision to buy that front IFS.

I did not have to open the holes up in my front end at all and I used the narrower version. That being said, I did have to modify the frame slightly to make the upper shock mounts clear. I have 10" width wheels on the front and was worried the wider front end would cause me to have to buy new rims. Of course after I bought it, I found out it would have fit, but no big deal either way.
