I am going to test this this upcoming weekend but until then wondering if any one has tried and if so likes, dislikes? Easy enough to switch back thus it's worth the try. Also wondering with the rear wing being farther being back in this config will provide better flight. Thinking this set up could promote the pendulum effect, however the 16 chassis I believe is 4mm shorter thus maybe beneficial in running this set up. I am to tired thus forgive me if the above makes no sense.
I tried shocks at the rear of shock tower and arms at my local track and didn't notice any difference at all , Im putting them back in front of the arms and shock tower
last thing you want is someone to rear end you and bend your shock shafts

[QUOTE=Slapjack;14402503]What springs and fluid did you use with those Pistons? I bought my xb4 used and the springs don't have any markings so I am assuming they are the stock springs. But I was going to order 1dot for the rear and not sure what for he front. Or will 1dot be too soft with those 1.6+1.1 Pistons?[/QUOT

1 dot rear and the kit front springs being 3dot. 35 to 37.5 front/ 30 to 32.5 rear.

TPR1. Thanks for the info. I received the same input on Facebook which the verdict seems to definetely be keep the shocktower and shocks in their forward settings. Got the brass hangers so will see how the help.

I tried the shocks on the rear as well and I think for the 4wd car the only time it will make sense is in severely low traction. otherwise having them on the front is always better

Thanks Norse... I just ordered the 1 dot rears and some 1.6+1.1 Pistons. I didn't order the 1.5+1.1 for the front tho cause Amain was out of stock. Do you think I'll be ok to run the 1.6+1.1 in rear and front or is that too much for the front? Maybe I could CA glue the 1.1 holes shut on the fronts and they will be just like regular 2 hole 1.6's?

I'm not sure either unless some motors have a longer shaft so you can flip the pinion to get enough set screw on there.

Hi, been searching this thread extensively concerning the issue of hexes. Looks like XRAY's +0.75mm 12mm front hexes with either xray wheels or 22-4 front wheels and +1.5mm 12mm rear hexes with xray wheels will give 245mm width in the front and 247mm in the rear.

I'm coming from team associated b5m and b44.3 cars and have a lot of b44.3 front wheels and b5/b44.3 rear wheels. Would love to be able to use them, but keep the same width's of 245mm in the front and 247mm in the rear.

Has anyone figured out which xray hexes to get to run b44.3 fronts and rear wheels?

Looks like getting exotek 1408 hexes will give a 247mm rear width if using ae wheels. But, haven't figured which hex to run on the front (xray or exotek) in order to use AE front wheels and get a 245mm width.

Thanks for any help,

Actually that sounds like a good idea to eliminate the 1.1 and thus just have a 2 hole 1.6. CA should work fine but someone may chime in with a better solution.

Yeah I don"t think you would like 1.6 + 1.1 up front.

Nice driving and nice home made carpet track my friend. Your buggy looks dialed in. The most important thing is how satisfied your are with the way the buggy feels, thus if you are happy and turning times you like I would change a thing. I believe when you have your vehicle set up to your liking its best not to get locked up in the over tuning game, thus spending time burning packs is more beneficial than over thinking your tuning. If she runs good and you like, don't change a thing just keep burning packs.

I am not sure on the B44.3 fronts or 44.3 rears offsets. I think you may find info on the first page of this thread. Wish I could be of more help concerning you wanting to dial in the correct 12mm hexes per using your B44.3 tire lot.
