I had the Apex 75mm installed on my old 135, great quality conversion. The only problem I had was that Discount Tire refused to remove or installed my wheels to do anything since had studs vs bolts that is called for EU cars... To get any service I had to remove the wheels at home and take them to get balance or fix when had puncture, etc.. Went to 3 different Discount Tire stores in my area and all gave me the same stupid answer.
