i want to replace my needle bearings as a precaution as I have no idea what mileage their on and my car gets a hard time on track and lots of road miles currently, I've previously replaced the snout bearings as they were getting lumpy so these must be equally shagged. I don't really want to pay the ridiculous shipping costs of zzp so will these be any good? http://www.ebay.co.uk/ulk/itm/301760003616 In reality if they last a year of racing I will be happy, and will replace as a maintenance mod over the off season. Thoughts?!
