When fitting aftermarket, or custom wheels, you should check for any clearance issues.
Incorrect fitment or Rubbing will wear out your tires, bearings, and cause other suspension components to fail or wear prematurely.
Offset is the measurement in millimeters from the wheel centre line to the wheel mounting face. More often than not, offsets are positive(+) where wheel styles tend to be flush or convex. Negative (-) offsets tend to have concave styling and the use of spacers.
The Offset, or "ET" (Einpress Tiefe translates to Press Depth in German), determines the distance between the centre of the rim surface and the face of the wheel where it is bolted to the hub.
WARNING: Incorrect offset can seriously affect vehicle performance.
This stock 4.5" x 10" Mini Cooper S alloy wheel has a POSITIVE Offset of 35mm. It would be seen as 4.5" x 10" wheel, 4 x 4" lug pattern, Offset of ET35.
This Minilite 6" x 10" Mini Cooper S wheel has a POSITIVE Offset of 15mm. It would be seen as 6" x 10" wheel, 4 x 4" lug pattern, Offset of ET15.
This Super Trax 7" x 13" Mini Cooper S wheel has a POSITIVE Offset of 7mm. It would be seen as 7" x 13" wheel, 4 x 4" lug pattern, Offset of ET07.
This Alleycat 7" x 13" Mini Cooper S wheel has a NEGATIVE Offset of 7mm. It would be seen as 7" x 13" wheel, 4 x 4" lug pattern, Offset of ET-7.
a wheel with NEGATIVE (-) 15mm OFFSET or ET would be shown as ET-15 a wheel with POSITVE (+) 7mm OFFSET or ET would be shown as ET07
Hello The Rose Petal Wheels weigh just some 2,8 kilos. What is the differece in weig to normala Minilite type 4,5,x10 racing wheel?
Is it true that they would be FIA approved for pre -65 Cooper S racers?
In some parts FIA lets some 1-2 % variation in sizes and if ahomologation tells to use 3,5" wheels then one can race with 4" wheels as in Austin Healey Sprite. FIA Historic comission changed the AH Sprite 5" wheels to 3,5" saying that thy had made a mistake 45 years ago. O´boy how they are wise , they find out queer things and claim their truth to be the right one. After this I sold my AH racer from Finland to Denmarka. Now , askin about the 4,75x10" wheels if they really are FIA approved also for pre 66 historic classes firstname.lastname@example.org Please email me.
