Yes they are as i said a few pages back.

No one reads this thread, they just hit the post reply button.

I already have a B4.2 ....
Braaaaa ......

What does advancing the motor timing exactly do for the motor on a 17.5.b4.1??

It depends on what motor you have. Some motors it'll give you more top or bottom and some just gives you more overall power.

Minus new shock towers 75% of us have the B4.2

JMO


Not gona make new towers .....

I'm sure you have a better inside scoop than me but without towers why wouldn't they have released it before Xmas? It would seem odd to come out with a car that needs shims or modifications to the towers out of the box.

I guess we will just wait and see

No special inside info
just common sense
To make new molds for a 10 year old design just ain't happening due to costs...

Which only means as I posted months ago ...
A new car for coming worlds , not the old design ....

Same with Airtronics AE horns. I think the AE horns are just a bit tight.

Nope new towers are coming and I hear (see) something about new rear arms.

There will be no new car. If a brand "new" car is release before June, I will change my signature to "Wild Cherry is God 2.0" for a month, lol.

B4 was released after winning Worlds ....

so your safe with the quote ...

B4 was debuted at the 2003 Cactus Classic (first big race, not when billy brought to tacoma in february 2003) and won its first Worlds in October of 2003 by Billy Easton.
