Just one more thing (additional to the PM) to copy from your FF03 is the height of the inner arm pins of the armmounts. This once made a huge difference on my KR-MF.

Is anyone still running the FF-04 Evo? I recently bought a new built (but unused) one, and have done a couple of local meetings with it on grey carpet. One was with a mostly kit setup (100k diff, 450 oil, kit springs, 1.0mm rear roll bar), the other was with several changes (500k diff oil, 1XB front blocks, reversed rear arms, Yokomo pink/blue springs, added a 1.3mm front roll bar). I found that the kit setup was responsive, but loose at the rear. The modified setup had a planted rear end, but off power steering was very poor. I plan to make changes to diff oil and roll bars to try and find a good overall balance.

However, the other FWD racers are all using the X-Ray T4F, and that chassis seems to be much more responsive, and has better drive out of the corners. Comparable drivers are up to 0.5s per lap faster than my FF-04 on a 10s lap, it seems like an uphill struggle to match them with this car...

If you recently bought the car, then you're not good enough at driving it yet to win races. Keep practicing.

Personally I prefer a loose rear-end with FWD. It's closer to 4WD in its ability to oversteer on command, though admittedly it's harder to rein-in the oversteer once it starts.

It's kinda funny to look at the T4F and see a rear bulkhead that is clearly designed for a 4WD chassis. I wonder how much work it would be to kit-bash a T4 and a T4F together to make a front-motor T4? (or a rear-motor T4, to keep my Tamiya XV-01 R company.)

How would you be able to do that, given that the Diff is driven via the layshaft pulley?

Most other initial FWD cars from other manufacturers did the same thing, in keeping their 4WD rear Bulkheads.

Curious if anyone else has done the rear conversion to FF03 rear tower and flipped arms like Kentech by chance?

I'm looking at my FF-03R and I'm not sure what the advantage of that would be.

Kentech stated it makes the rear of the FF04 work more like the TRF TC cars as it uses the same arms but flipped, which did not make sense designwise.

I was one of those nutjobs who bought into the clearance FF04 Evo Black Editions on TamiyaUSA's website.

.. I built it last night.

So, there are some exclusive bits to the kit. The aluminum bumper bumper mount, the shocks, and.. a few other bits.

It was really pleasant to build. Biggest surprise, was just how many parts weren't use. Both NN trees are 90% full. and the transmission tree came with a complete, second transmission case. I suspect it's part for the XV01? All the suspension bits are carbon too.

In the "it's nice to use" category. There's holes in the chassis for popping the diff out, and for reaching the swaybar from the bottom of the car.

.... the color of all of the aluminum.. is black. Every bit other than the shock bodies.

Same here. In the amendment for the shocks and metal mount sheet for the instruction it references that the parts are not available through the tamiya site. I'm sure this includes the rest of the black parts if replacement parts are needed.

I can't wait to drive it. Not sure whether to get the tamiya civic body if I could find one. Was looking at the bittydesign hcf or protoform. europa.

I saw it in pictures that the black edition didn't have aluminum suspension mount (blocks) but rather using plastic while the FF04 Evo (blue) uses aluminum. It this correct?

As seen here:

Yeah, the suspension mount blocks are plastic.

Damn!

What was Tamiya thinking when they didn't include the aluminum blocks when all other FF car kits have the aluminum blocks included as stock? Even the FF-03R and Evo have aluminum blocks which are essential to the kits.
