The Radar Dimax R8+ is built for ultra high-performance vehicles, using an asymmetric tread and silica compound to deliver enhanced handling and grip at speed.

    Huge thanks to TK once again from Hyper Drive for always looking after me whenever I need wheels or tires. He’s helped me out a lot with my Evo, and now with the Eclipse as well. He always provides great customer service, is easy to communicate with, and makes the whole process simple and stress-free. I really appreciate how he always sorts me out and takes the time to help properly. Definitely a 10/10 experience every time — highly recommend!

    Had Jay come out and fit and balance a new set of tyres for me. Top bloke, turned up on time, got straight into it, and had everything sorted in no time. Did a great job and the wheels feel spot on. Really easy process from start to finish. Would definitely recommend Hyper Drive, and Jay especially. Cheers Team!

    Awesome experience with Hyper Drive Mobile this morning. Steve was super friendly and easy to deal with, and made the whole thing really straightforward. He turned up earlier than expected and had the one new tyre fitted in under 30 minutes. Was also stoked to see he’d polished the tyres and topped up the air in all the others too. I didn’t even realise that was part of the service. Such a nice extra touch. Really good customer service and just an all-round great experience. Thank you!

    I used the chatbot as was so confused what battery I needed. Was so helpful and found the right one. Great service, shipping to my work address, which is an added bonus. Great price for the battery, didn’t know I needed a new one till mechanic flattened my battery.
