davidc92 Posted 22, July 2021 Report Share Posted 22, July 2021 Hi, I’m about to take the plunge and purchase either an RS265 8:08 or a RS275 cup premium. Is there any discernible performance difference between the two? Not really concerned by the extra power, because this can be eclipsed easily with a tune. More so talking about any dynamics/handling difference between the two (apparently cup premium has lighter weight suspension components). I imagine it would be hard to tell any difference on a test drive. Cheers, Dave Quote Link to comment Share on other sites More sharing options...
