Just heard from our Australian dealer a customer of his took it upon himself to do some very serious testing of Rota wheels.
He bought some Grid Drifts, 18x9.5 ET30 Fr 18x10 et15 Rear , and threw some full slicks on.
He then went and gave it death on a track, after having his car tuned to produce around 600hp.
Not only did he weigh the Rotas and Slicks against his standard wheels and find them some 10kg lighter per corner, but he really felt the difference in terms of serious lap time improvements, as well as the feel and handling of the car was significantly improved.
Once he finished this track action, after being so slated for running these wheels previously, he took it to a whole new level, and got them ultrasound and xrayed, to double check their integrity.
These wheels are random set, sent to him from stock, with no prior knowledge of his plans for them...
I will now let the pictures speak for themselves.
As you can see it's no lightweight low-load track toy, and the xray shows not only a total lack of defects, but everything to be in excellent order and entirely uniform. The track time was maximum attack, taking full advantage of the curbs.
