Then i should start making friend with their staff. Most probably can get something at discounted price...hihihi
If the factory can sell direct, then okay. Like my ex company, the factory only manufacture for export and sales to local sales company for local sales. Even factory staff who wants to buy the goods, need to get then through the sales company as the factory cannot sell direct...

Nope the 5% difference he mentioned is not the rolling diameter difference but he expected around 5% difference in dyno results! The 20' tyre he used was 255/35/20 while stock 18' should be 235/50/18 which is actually bigger rolling diameter than the 20' tires! So despite running bigger rolling diameter, it actually got 20whp more than the heavier 20' setup with slightly smaller rolling diameter. To me it's pretty conclusive. I had seen many other tests long time ago but just cannot find them anymore.
the 5% I'm talking about the size difference based on tyre profile and wheel size. Not what the dyno was referring to.

It's not conclusive to me. But to each his own.

Hmm I think that should not matter much if at all as long as the rolling diameter is about the same. Weight on the other hand plays a significant role.

thanks all.
I'm looking at advanti rims because most aftermarket lightweight rims do not have pcd 4 x 114.3 which renders limited choices.
have you all heard from Kean Lee Hin store at jalan ipoh, which is one of the authorized supplier for Advanti rims?

Will the gap between the fender and the tyre look weird with aftermarket lightweight rims?
Take ur time if u really interested with aftermarket.
But not much fancy choices for 4x114.
Took me 3 mth to search for right ssr type-c 4x114.

Bro, you're wrong, wheels diameter is different but rolling diameter in that video 2 is NOT 5% different! As I said earlier, the 18 is actually 1% bigger rolling diameter yet generates more whp.

In video 3, one of the lighter rim is also exactly same diameter and tire size so again exactly same rolling diameter.

Ori or not...susah to differentiate just by look.
Like mine ssr type c.
Rim weight is 3.85kg , not too unbelievable cheap.
And trust between buyer and seller.

The spec on paper for 15' is not that light. It's around 9.3-9.7lbs or 4.2-4.4kg. Still very light nonetheless. The 15' which is under 4kg as far as I know is only Racing Hart CP035 at about 3.9kg.
