guy has a set of fiske wheels for sale 19 x 8.5 et 45 19 x 10 et 50 would these fit on the v12 with / w/o spacers or ? thx
Henry- Too narrow in the rear, but they will bolt on fine. Because the rears are 1/2" (1/4" inside and 1/4" outside) narrower and offset ~1/2" more inwards than OEM wheels, they will look like kiddy car wheels without spacers. Not recommended, even with 25 or 30 mm spacers. Never use wheels smaller (narrower) than OEM is a good rule of thumb. 550/575M/Superamerica 550/575M Five Spoke/Modular 18”, 5 X 108 mm Front 8.5J X 18 ET 43.65 mm, Rear 10.5J X 18 ET 32 mm 575M/575 Superamerica Five Spoke Modular 19”, 5 X 108 mm Front 8.5J X 19 ET 43.6 mm, Rear 10.5J X 19 ET 32 mm
Henry, if you like the style, Fikse will custom-build a set for you to your specifications and requirements. Barry
I have Fikse Profil 5's for my 550 that I haven't mounted yet. They're 19x9" in the front and 19x11" in rear.
This is not my car, and I photoshopped it to sit a little lower...but it's the look I'm going for. Image Unavailable, Please Login
So put them on! When I tracked my 550, I considered ordering Fikse Profil 5s for it. But then I got my Challenge car and dropped the idea. Here are SAC wheels with slicks trial-fit to my 550. They're similar to the Fikses... . Image Unavailable, Please Login Image Unavailable, Please Login
I have a ton of parts the 550 is awaiting. Local indie shop is backed up though and I want to get a fresh major in then dyno test before doing modifications. Weather sucks here still anyway so not in a huge rush.
thanks guys i guess they were for a 360 but super cheap was the only reason i was tempted.... terry - offsets confuse me... the bigger the number the further "IN" the wheel is ? they would have looked better/worked if the offset was a 32 ?
https://www.rimsntires.com/specspro.jsp This is a pretty good calculator for wheel and tire size calculations. Diameters, offsets, revs per mile, etc. Hope this helps....
Henry- Our wheels use positive offset to the outside of the wheel center line, so the bigger the ET, the further in the wheels sit. Easy to visualize if you make a simple drawing on a piece of paper. Draw the wheel width with two lines and then split it in two. The middle of the wheel is the point from which offset is measured. Then mark offset where the hub line will be, in our case towards the outside of the wheel. Doing that, you can see that the bigger the offset to the outside of the wheel, the deeper that wheel will sit on the hub. This image will help you visualize what we are talking about. The outside of the wheel is on the right and the hub line is marked. Image Unavailable, Please Login
