I am running 18x7.5 technology twist with 225 tires. What size wheel spacer do I want to run to fill out the front wheel wells. Thanks

I think those are ET52. No spacer is fine.

Yes I forgot to state the offset, but you are right it is 52. I saw another car that had Classics II's on it with front wheel spacers and it put the wheel just a little closer the outside edge of the fender and it looked good. I was thinking of doing the same.

First of all IIRC your wheels are not "Technology" rims as that term is only for the hollow spoke version of the Twists and I think come only in 8" width.

As far as spacers, I know a 9" ET40 fills out the front wells nicely if you are willing to roll the fenders slightly...this would be the equivalent of adding a 30mm (ie 37.5/2+12) spacer to an 7.5"ET52 wheel. Or if you don't want to roll the fenders a 8.5" ET46 works pretty well and that would be equivalent to adding a 18mm (ie 25/2+6) spacer to your Twist wheels - I don't think you can go more aggressive than this w/o rolling the fenders. Hard to really see but the rim in the sig pic below are 8.5" with 235s but the current set up is 9" with 245s.

But IIRC if you use anything wider than 7-8mm you will need to use spacers that have the studs, rather than just pressing in longer studs onto your hub and using a spacer plate.

You can see from the angle in this pic that the front wheel wells are not very filled with 235s on 8"ET52...I've thought about adding an 8mm spacer but will probably sell the car

Hollow spokes also came in a 7.5" ET 50 version. I have a set for my track wheels as well as the stock 8" ET 52 for my road wheels. The 7.5" versions were installed on early 996s and Boxsters.

I am not aware of any factory 18x7.5" wheel that has a 52 ET offset. Should be a 50 if it is 7.5"

Hmmm....didn't know that! I was under the mistaken impression that Technology wheels only came in 8"ET52 but solid twists came in 7.5" and 8" ET52. So the 7.5"ET50 Technology wheel was a 9X6 application. Thanks

Here is a pretty handy chart I use to compare Porsche wheel weights and part numbers.

Just click on "Felgengewichte" on the bottom left. You can opt for the English version.

Right, sorry, 7.5 = ET50 and 8" = ET52 on the hollow spokes.

Van1, your are right I looked at them this morning and they are 50 ET. and yes they are true Technology hollow spokes, smooth on the back. Which makes them off an early Boxster/996 but carries a 993 part #.

Also after doing some shade tree measuring, what I am looking for seems to be about a 15mm spacer. I am running a RS spec alignment, so with a little negitive camber, this should not rub. I do not want to roll the fenders though.

What I was hoping for was someone that had a simular setup and just say " run x and it works fine".
