I'd get ahold of the guys at Topline and confirm exactly how much backspacing you can use. If 6 is still okay or is it already at the boarder of "your going to rub at extreme motions of the suspension". If 6" is already at an extreme I'd try to atleast hit that not over. But this may not be the case it might be Topline saying "hey this works but we don't want to be responsible if somthing happens, though 6.5" is still okay".

Remember too that 6mm is the wheel into the springs not including tire bludge. The tires tend to buldge a little about 1/4 inch or so this needs to be taken into account to. Because these strut dicate your requirements I'd get as much info on them as possible, how much is exactly too much. Once we have this the rest is just full-filling those requirements.

But did you understand my calcs?

Yea okay, so I looked at Lanners site. Those measurements he gives you are track increase pre side. So .6"mm wider on each side.

You want the ones that will increase the track the most, it seems like the bolt on brackets and the billet hubs will do that, but this by my calcs may not be enough, that extra 6mm remember?

So may be talk to him and see if he can increase the hubs to provide more of an increase or, just get the stock hubs modified and use a spacer.

This way you have the increase of the stock kit which is 2mm, then save some cash and spend it on some spacers.

Choice is really yours, the real problem with all of this is that it works okay on paper may not be what actually fits. But all of these questions being ask are along the right track. I spent a lot of time working out the details to make my setup, and though it may not be perfect I know it will be better than those who didn't.

But to do this right you need to know what your dealing with, you need the requirements. There is one option here that no one has said yet, may be try and get smaller rims. I know the apeal of larger rims, but with the 8.5 on a super it's sort of new territory. I don't own a super, and frankly math is easy, but me not having experience with a super you'd probably be better off talking to someone who has done this successfully.

Oh yea and the over analyzing thing well yea...when I started doing this I got some weird advice and some completely wrong information. One guy argured with me that a larger offset with spacers is the way to go, after I explained to him why its good, he realized that my point, that a wheel with less offset is just as good and eliminates the need for a spacer. The main problem with this stuff is that we can't go to far in, so if you want wider wheels, well, you gotta move the wheel out. In particular the stds can handle things differently as now you can use large spacers and then narrow the beam to make up for the inceased track, but supers are a different beast. Just remember sometimes just fitting isn't enough, you may want to turn to.
