This is my wide rear flare design. They fit very well and cover up to 188cm wide (outside tires) backs. Fit perfect with rears with 25 to 26" diameter.
Note Allans car has 17" inch and my car has 15" on both cars the rear wheel well has the original style ellipsoid shape, which in my personal opinion makes the car look much deeper.
You can see on the pics how well they fit and how few putty is needed. If you check my thread you will see the installation in detail.
Available within 2 weeks . Made to order by an specialist working for the DASA making carbonfiber parts for them. if you are interested PM me.
Thanks
TOM
