it fixes perfectly at any kind of wheel, drift or touring, has excellent colour, blue or red, and they are much better from the standard plastic ones that your car have. I bought a pear of disc breaks and unfortunatelly i cant use them both. as well they look great if you have star rims than the multi radial rims.
This set is not too bad, I use it on my TT-01
Pro's: looks cool (when you take off the wheels), It has less friction then the standard plastic ones, You aren't puzzeling all the time on how to fit the washers, they don't stick to the wheels.
Con's: none, But I can't say I really need them, maybe if you have a faster car then a TT-01 these are usefull.
All in all this set is okay but if you'r speeds aren't really that high these aren't a really needed Hop-up
