So like the pre two piece suspension pieces, the flipped r/f bridge for the belt clearance.

Is this with a aluminum chassis car or a carbon plate car? Without the -.75 hexes you must be over 190mm, thats pretty wide.

I would use blue loctite - lot of vibration in mod..


Almost done with the build - great job Serpent!
I'm currently building my 4.0 now and the build has been very good so far but because you were asking about the -.75mm hex hubs, I installed a pair of them on the rear just to see if they fit properly. Good to go!

Other's had posted they will work but I just had to see for myself

Yes, around 189 mm with -0,75 hexes in front. The difference on track between carbon 2.25 and alu isnīt that big. I will try the carbon 2 mm on carpet. I think the stock 2.25 mm makes the car too flexy on carpet.

The only bad thing about the shocks is still the adjuster when assembeled with the o-ring has enough drag that it will turn your shock if your not watching. I just don;t use them and haven't had a issue with them self adjusting during a run. Paul was thinking that we could possibly sand the caps down slightly to squish the bladder just enough to prevent this, and it would take much thats for sure.
.
There are 2 other options:
- glue the nylon top part to the shock cap.
- but a better idea is to cut the o ring in the adjuster and remove a small part. About 3 mm already makes the drag a lot less.

You only need a very small amount of drag. Probably without o ring works in electric as the spring will most likely always be in contact with the adjuster, but in nitro, the harder springs require drag in the adjuster.

I am looking to purchase a kit not sure on brand, can anyone post some information as to how the new 4 performs compared to the 3 ?

If you are on carpet the 3.0 is supposedly the way to go.

A safe bet is 3.0 on carpet. If asphalt i think 4.0 is a very good choice. And i think the 4.0 are good enough for carpet anyways. But it is still too new to say if it can work well on carpet yet. I myself use 4.0 with 2.25mm carbon chassies, i feel like it works good. But the pros say it needs tweaking first.
I will try new things tomorrow and hopefully get the car dialed for carpet.

The 3.0 and 4.0 are so similar that both work just fine on carpet. My 3.0 on carpet with Alu chassis is just as good as my 4.0 with Alu chassis or 2.25 carbon on carpet. The 4.0 is a better car overall particularly the motormount which doesn't tweek easily with board contact like the 3.0 motor mount does. If you are buying a new car for sure go with the 4.0 kit (not a 3.0). Just decide what you'll be racing on more asphalt or carpet. Alu version for carpet and carbon for asphalt. It's really that simple. The 4.0 does work very well on carpet with the carbon chassis too.

So to me the answer is easy. 4.0 carbon! I hope you come and join us it really is a fantastic car.

So your all finding the 4.0 a superior car. Easier to tune. Easier to drive?
Does it have a broader window of set-up...
Is the rear end more stable? Or able to be dialed in more readily.

The geometry between the cars is the same and so the results on the track are similar. My 4.0 does feel a better car to drive and I have (generally) a little more rear traction meaning I feel like I can drive the 4.0 harder than I could my 3.0.

The main benefit I've found is the flex characteristics of the car is much improved and more uniform. The new motor mount (shocks aside) is the best chassis improvement which prevents the chassis tweaking on minor board hits. The 3.0 motormount used to tweak every time you hit the car which was a PITA! The 4.0 is a definitely improvement over the 3.0 but it doesn't drive massively different nor does it setup much different than before.
