They are originally made by ETA Beta (Italian manufacturer of the centres) but have been completely refurbished to with barrels / lips to give the following sizes:
Front 18x9 ET49
Rear 18x11 ET52
These compare to the OEM Widebody Turbo Twists which are:
Front 18x8 ET52
Rear 18x10 ET40
This means that they will "sit" compared to the Hollow Spokes as follows.....
Front -10mm inner clearance; +16mm outer
Rear -25mm inner clearance; +1mm outer
I have no real concerns over the rears as they will need the 15mm spacers I've already bought for the Hollow Spokes which will give...
Rear -10mm inner clearance; +16mm outer
I'm hoping losing c10mm inner clearance will not be an issue as its within tolerance for most cars but again I'm still learning about the 993.
The fronts are the bigger concern for two reasons. Firstly the offset of +16mm outer clearance. Again as I'm not used to the 993 this may be pushing it a bit but normally you are safe with +15mm over OEM spec wheels without considering suspension setup, camber settings, wheel stretch etc.... so I'm hoping this will be OK. Secondly is the 9inch width. The 4 wheel drive 993 already has relatively heavy steering so I'm not looking to do anything to make this heavier. Fitting wider front tyres would likely make the steering heavier so I'm hoping I can get away with the same fronts as I have on now (I think they are 225's). I may need a little stretch anyway with the offset ?
I'll not be trying these on the car or considering tyre specs for a few months in all probability given everything else I have going on at the moment (new job on top of house move :roll: ) but it gives me something to look forward to fiddling with in the new year.
I can't wait to see what these look like on a WB 993. They are very similar to the RH/Speedline split rims so I'm hoping they look as good / better with the deep dishes.
