Alvin: Yes, correct ! it's down to driving style .. Having said that, I have to say that many experienced racers here like this kind of setup. The World Replica kit will include this extra spacers and a new rear FRONT suspension block (installed over the front belt, instead of under).
I really hope you can make it to the Indo Reedy Intl Race in August, I am sure you will get lots of tips from the World Champion. FYI, Some experienced Australian drivers have confirmed to participate.
Sorry, I am not able to post (on my website) any pictures of the latest World Champion modifications. Well, it goes with title isn't it! But I might be able to tell you more thru emails.
Cheers!
