I just got both screws started and was able to snug them up one at a time. As it spins, it should snug the other side up enough to stop the spinning...at least it did for me.

Well i like the idea because it is less likely to let the shaft indent the aluminum bulkhead through use, or once tightened... but theres no tab on the other side (for obvious reasons). I have already stripped a spurgear in a Photon i drove before... and seen many other Photons strip spur gears. Im just trying to avoid that i guess...

I think im gonna grind that tab off, mod the length of the shaft, and use an XRAY steel washer on each side of the layshaft. Im already using a flat head screw and cone washer on each side to make sure the shaft is 90 degrees of the bulkhead once secured.

Has anyone heard of someone machining some front and rear bulkheads out of steel? Nothing fancy. Just exact replicas. I would buy them if so...

If there are any of you guys that have a slew of HPI or XRAY springs and are familiar with them and their performance (or hate to invest in new springs because you have a lot of $$ spent already)... i wanted to let you know you can get them to fit with a little custom work.

My kit front TOP spring is 24.90mm in length (this will of course vary with coil count) with a 14.10mm ID.

My longest HPI spring (non progressive) is 27.5mm in length with a 13.95mm ID.

My longest XRAY spring is 27.15mm in length with a 13.85mm ID.

Lower spring perch ID is 13.10mm, so spring ID isnt an issue.

If you mind how far you screw the shock shaft into the lower ballend you can make up some of the length difference there, for threaded body adjustment. Regardless, the added spring length needs to be compensated for at the upper shock mount, to be able to achieve acceptable ride heights.

The fix is easy... drill 2 new top mount holes 3mm lower, center to center in each carbon tower. Slot the bottom 2 holes in each carbon tower. Be sure to use flat head screws and their cone washers if you arent using the swaybar mounts. This will raise the shock towers to make up for the added spring length difference, and allow you to use any spring you wish.

The 3mm will also raise your rear body mounts. Body post holes are close to 4mm adjustments.

I use the hpi pro4 set from time to time and found there is enough gap with the collars alone to stay within 4.5-5.5 range of ride height on rubber tires.

DAVEW... stop dialing yourself out! instead of going through all that trouble with springs, the TOP springs are cheap enough already...

doing that mod with the shock towers, i think the results will be changing the roll center a little.... step back, give the dremel a BREAK!

ARV! When have you know me to dial myself out? Youre right, raising the shock tower will change the shock ratio... i just didnt see the need to get that detailed.

Nah, im just trying to learn from seeing the problems others have had... so when i drop the car down its done... and done right. And wheel nuts are overrated...

X-ray springs will not work.. I tried and it will not hit ride height. (rubber tires) might work with foam

Works like a charm

No the lipo bracket does not fit, there aren't holes for it.

I had a similar thing when using xray and tamiya springs, tried a different ride height adjuster, but in the end checked the shock shaft itself... there's a 4mm 'stub' on the end where you thread the ballcup on, check if yours has this and grind it off. No more ride height issues.
