Gents,
I am looking at some alternative wheels, they are offered as ET16 rear which is correct for my 86 turbo but the fronts are ET40 whereas my fronts are ET16, I presume they will not fit ?
Anyone help me out with this one ?
 
16mm is WAY sticky-out: are you sure? Front seven inch rims Id expect to be ET23mm, so 15mm-17mm spacers will make them right.
 
Thanks 944 man.....DOH got it wrong, i am looking to buy some 17" Fuch Reps the rears are et16 which are the same as my 17" cup reps et16 so that's ok The front Cups are et23 but the sellers fronts are et40 will they stick in/out 17 mm, will they fit ? Early 86 turbo BTW
 
Rich New ones are 7.5 font 9 rears, existing ones 9 rears and unsure about the fronts as they are down at my other garage 7 or 7.5 ? I have a feeling that they will be 7.5 as they are fitted with 225 rubber. Jim.
 
Theyll be too far in by 17mm; but this assumes that theyre 7"s wide. you add or subtract 12.5mm for every one inch of rim.
 
So long as its that way round I've used spacers before on other cars to fit different offset wheels and didn't find any problems. (except I had to use longer wheel studs which I'm not sure how you'd do with a 944 as they're the other way round? Do they unscrew from the hub?)
 
The new ones are 7.5 ET 40 as opposed to 7.5 ET 23 exsisting so a 17mm spacer is needed ? though if originals are 7 a 6mm would sort it..............corecto mundo ? Edited due to Shiraz ! Originals are 7 x ET23 new ones 7.5 x ET40 gain 6mm due to rim width difference of half an inch, so ET now equivalent to ET29 Leaving 11mm difference so a spacer of 10mm will get them as near as damn it ?
 
Ben, You will be ok with 6/7 shims to use exsisting nuts, i have them on the rear of my 220, after that you need correct spacers which bolt on to the hub via studs, the new spacers in turn are fitted with other studs at the correct PCD the bolts used for bolting to the existing hub sit flush as it is a short nut in a countersunk hole.......make sense ?
 
Yes. Neat trick but I assume you have to cut the studs or you'd be a long way out so that makes it a permanent decision to use those wheels... not that thats a bad thing with a set of Fuchs[:D]
 
Ben, Nah, the spacers are a 5 minute job to unbolt, not a permanent fix,you bolt the spacers to the existing studs, the spacers carry a second set of studs to bolt to, these Fuch are replicas but come in 17". Pretty sure the car would look the mutts with these on,polished dishes and black centres, not to sure about the quality though, do not think they will be anywhere near Fuch quality, read on the web that no real problems but some run out issues.
