Just remember, the purple/grey combo with 2-hole pistons will likely feel MUCH stiffer on the 415 than it did on the EVOIII. Though the cars share many parts, the geometry is quite different. Personally, I found the purple/grey to be too stiff.

Yeah we've met ARUN. Kumpol told me about the softer setup. But I've only had 4 battery packs through this car on carpet (2nd qualifier, 3rd qualifier, main, practice after main. I missed the 1st Q setting up the car hehe). Ran great from the start. I'll give the softer setup a try this weekend since I have 2 sets of shocks. I'll see which one feels better and produces better lap times. Our track is not as small as yours.. nor as technical. It's more of a HorsePower track like the Snowbirds. So I'd be interested in seeing how the softer setup works. I'll post my findings Saturday night.
Though we do run on an extremely tight track, the main difference in a softer setup is in the behavior of the car throughout a turn. While a stiffer setup would still turn in and come out well, it would not rotate nearly as well.

Another great thing to try is rear pro-squat throught the rear roll center blocks. I currently have 4mm of shims under my rear-rear block, and 2mm under my rear-front block (in addition to adding 2mm of pro-squat, I raised both 2mm to help rotation). I found that the pro-squat helps the car be aggressive going in and smooth coming out.

I have more tricks if anyone is interested, but I need to finally get to bed.

How do you keep the belt from rubbing the rear front-block with it raised so high?

Also, do you find that the prosquat gives you more side grip or forward grip?

And are you running stock, 19t or mod?

What i do is i flip the block over, then spacer it up this means the belt now passes under the block. To do this you have to file the corners off the spacers. Rick

sorry there was a spelling mistake,lol.theres no anti roll bars all round.
the car gives more grip when i lay the shocks down.
i have used a front anti roll bar this reduces grip too much.
its only upon turn in that its oversteering.
the back is sliding slightly and scruubing off speed.
ive increased rear toe in to 3.5 degrees in from 3 degrees.
i will see how that goes,thanks

Hey does anyone know where I can get the A bridge front block from. I have tried several local sources, (Ultimate Hobbies, Speed Tech and So Cal Raceway) none of them have it. Any help would be appreciated.

Err i find 3.5 degrees rear toe in is wayyy too much. I always run 2.5. If your finding the car is oversteering lenthen the wheelbase by moving spacers around on the hindgepins. Is this for rubbers on carpet by the way? and what are your running upfront? 1 way or spool?
Hope this helps.

I do not think that raising the rear-front by 2mm caused any belt clearance issues, but I did grind my block from when I had 4mm under the same rear-front (at one point I tried anti-squat, which was also very effective). So now, I have a C block in the rear-front that already has material removed for belt clearance.

Flipping the block as Rick Draper mentioned will work with 2mm of spacing, but will not work with much more when using the old-style rear bulkheads. The new "MS" style bulkheads are curved, and happen to give more clearance.
What you must do in order to flip the roll center block:
---first file the top areas of the block where the screw hole is flat
---5mm of spacing under this area (with the block flipped) will yield the same roll center as before. You can add the 2mm from there.
I think that it is more simple to just remove some material from the block.

The reason that the pro-squat helps our car on carpet with foams is because it frees the car up going in and allows the car to be smooth coming out and on power. This way, the car is not scrubbing speed and is rotating extremely well (not "too stuck").

I usually run either mod or 19t, but I am running mostly 19t right now. I rarely run stock.

I may take some pics when I get home later tonight.

Keith, I'm not sure but I think the new World Champion Parts Kit comes with it. I saw this on eBay.

Have you guys ever snapped off that 1.6mm screw in the wheel hub? Its pretty cheap so don't crank it down to tight. I think I'll try drilling it out and tapping it with a 2mm or just leaving it as its not really necessary other then to hold it together when the wheels are off.

Whatup Neil. Hey the worlds kit only comes with the rear blocks not the front bridge blocks. The rear blocks dont have the bridge to clear the front belt.

Hope you and the family had a Merry Xmas.
