Std XX-4 and Worlds differences
 

What are the differences between an old Skool XX-4 and the Worlds Edition?

Cheers,

G

Full graphite (chassis and cover set with lowered battery and motor slots, wishbones, front and rear towers), inboard toe in, titanium hingepins/turnbuckles, composite outdrives front and rear(if it's a new car from last few batches outdrives come with saver rings as well), threaded shocks, HD belts, tungsten carbide diff and thrust race balls.

Common upgrades:
Front CVD's/LCD's (you will need to change the front wheel bearings use losi or associated rear wheel bearings)
Titanium steering turnbuckle
Spur gear to 78-82 (as the kit purple 84 can catch the bottom of chassis)
One wat front diff (you need to replace front drive shafts with CVD's/LCD's)
Red rear and Silver front springs

The upgrades listed above are not essensial as the car is very god in kit form.

Cheers for that,

What parts are different for the rear toe-in? Does the Worlds car use BK2 wishbones?

Cheers,

G

Yes bk2 or xxx wishbones fit

So which hole is used on the BK2 bones if both fit?

What other parts are different?

G

You can't use the outer hole as it makes the car too wide, so most just cut it off as it runs very close to the inside of the wheel.
The rear toe-in blocks are the same as the XXXcr, you just remove the webbing material. You will also need some XXcr rear hubs, they are the ones that come with the worlds kit so are easy to get as they are 0deg toe-in.
Hope that helps
