People throw tire and wheel sizes around but they usually dont show offset.

Does anyone know where I can find a dependable chart.

Shocks don't make a car stiff.... Springs do. And the stiction from not TRTproperly installed bushings can really contribute to spring rate

The 7R wheel on the chart is basically perfect offset and the reason a real 7r will fit. Of course a real 7r is 1k per a wheel.

The 14 inch windmill that was stock on 6 cars was in my opinion used because it also has perfect offset. It is 2mm different than a 7r and a great fitment. It is also the cheapest fuch you can buy. It is also period correct. It will also give you a smoother ride as most tires available in 14 sizes have a taller sidewall. It also is a "deep" look wheel and cool looking. It does have down sizes. It is the least performance oriented due to the smaller diameter. Smaller width. And lack of tire selection.

All of the 5bolt Fuchs and cookie cutters have the same offset and will fit an undamaged stock car

I am not aware of any 6x14" fuchs. There is 5.5x14" fuchs in other tables, offset is 41mm.

I don't agree that 49mm offset of 7R is perfect, or even very good. However, if you like that, any of the following should also be useful:
* 52mm, 6x15 phone dial
* 52mm, 7x15 phone dial
* 50mm, 6x16 early boxster

I believe the best offset is 35-40mm. Keep in mind that all cars are a bit different. Also camber you are using (particularly in rear) is important.
