Narrow body fuch 7R fitment, anyone running fuch 7R wheels? Options

[tomkirkcis]

.I have been running searches for a couple of hours but can't find any info on fitment of 7r fuchs on a 914.

I have a narrow body 1970 factory 914-6 that has a hot 3.2SS motor and a close ratio LSD box Dr Evil built for me. It currently has 205/50 on 6 x 15 fuchs. Not enough tire .

I have some AA metal flairs I got in a group buy a couple of years ago that I inteneded to install. I have four 9 x 16 fuchs that I was going to install all around . Certainly would take care things

I am having second thoughts about installing flairs. It is just so much fun having a stock looking 914 with a big motor.

I have access to a set of 4 7r Fuchs with 225/50 Brigestones. These are the Fuchs with the large backspacing

Is anyone have 7Rs fitted to a narrow body?
What tires can you fit?
What spacers?

Thanks
Tom

The safer and more complete way is to disconnect the strut bolt so you
can move the arm easily to the maximum. From the spring rate you can
approximate the travel, and then figure a bit of side-side movement of
the tire under load as well.

This was good advise.

As Eric had noticed, my car has the factory GT stiffening kit installed. This narrows the wheel well a tad on the inside. I tried the above technique with 8.5mm of spacer under the 7R's with 225/50 Bridgestones . The verdict is in.

They DO just fit on the rear of my car. I had no contact on full movement of the trailing arms with the strut disconnected. This is more vertical movement than would be encountered while driving. I do not know if side to side movement while cornering would cause contact. It very well may as there is very little room to spare, both in or out.

If I did not have the chassis stfifening kit, I think I would be able to get away with a 5mm spacer , or maybe a little less and gain a smidge more of outside clearance. Someone also commented the Bridgstones side profile tend not to be as wide as some other brands so that may help with the fit.

I will probably order proper length studs and try the car on the road. I live in Massachusetts so this will not happen for a few months. So as other people have pointed out, each car is different.

I will report back

Good work, Tom. What is your rear camber?
