Can homebuilt be faster than factory-built? | 818 vs. Boxster S | Articles

1000 pounds and 2 seconds faster on a road course. I would have thought the difference would be more pronounced. What does everyone else think?

Agreed. That doesn’t seem like a big enough difference. Same tire compound? 

Same tire compound I think but Porsche’s tires are wider by almost half an inch front and back.

Also, the Porsche has more HP, and more than a few years of sports car engineering prowess behind it.

Edit: doh! I only remembered the second half of the statement that seems plenty contradictory:

“Aside from a set of Bridgestone Potenza RE-11 tires, it’s still stock. Our 818 rolls on Yokohama Advan Neova AD08 R tires, making this a fair fight right down to the rubber.”

In reply to Robbie :

Oops missed that.

That makes it pretty disappointing.

Goes to show weight isn’t that important if the car can handle it.

I imagine that someone who isn’t as dialed in with the Porsche as Shields might find the performance gap to be greater.
