One great thing about the XTI is you don't need any special spacers to adjust ride height. Just take four washers of a known thickness and space the entire front sub-frame up from the chassis! Instant, consistent ride height adjustment without making the car more fragile or needing to unthread big screws from plastic parts over and over.

I am using the small diameter shim that is .047 inches thick.

For those "fast guys" at the Nats, where did you end up on center spring?

Looking for those elusive last tenths!

In testing at the Plex club race last night, I went up one spring size and picked up some on power steering. Also discovered I was definitely over geared.

The circle was one of my slower parts of the track, and getting steering there helped.

What other things do you generally try in med/high conditions to get on power steering WITHOUT making the car overly aggressive?

Do any of you care to share a setup sheet from Nats?

Thanks again for your help!

Here's the setup I ran from the nationals. Mitch ran something very similar.

Altered ego chassis/xti rear pod and top plate(short/short)

5* front blocks with 2 shims forward
CRC Blacks cut to 40.3mm 1/2 dope
3.5mm RH
.50 front spring .5mm droop
.5* camber

Red center spring(new one)
30wt oil
2mm pod droop
41.3 rear tire
3.5mm ride height
CRC Graylow rear
Max width
20k in the tubes
.50 sides outboard just touching and tweaked

Thanks!
Do you typically run the same setups in 13.5 or make changes for the slight speed differences?

Very similar. Most guys run different tires like blue/green rears in 13.5 and magenta fronts in 13.5. But other than that the cars are very similar in setup.

Alter ego conversion questions:

Other than the graphite chassis conversion parts, can someone provide the list of additional parts/part numbers needed to convert a stock XTi to an Alter Ego?

Thanks in advance,

John

You need the full-length side links, I think the part number is the same as those for the XL and Xi.

Bottom line: try it! Don't take anyone's word on what something should do. Prove it to yourself.
Brian, I have now run your setup and I think I fully duplicated it. I finally was able to mount the battery inline with the speed control at the rear by the motor pod. I came up with a way to hold the battery without using the tape, but keeping it away from the servo. That turns out to be more simple than first thought. Just two screws mouned between the servo and the battery. They are 4-40 flatheads, about 3/8 to 1/2 long, with the smallest standard nut on top. The nut fits the curve of the battery case so everything fits down to the chassis.

Used the BSR white (CRC yellow) rear tire and the black front tires. Changed the front doping a little to adjust to conditions. This car is more aggressive than I was able to make the original Xti. I think the shock angle contributed to this. I still had a little push, especially early in the run, that put me behind, but I was able to catch up when the front tire hooked up. You are right that the front tire starts to grip more as the run goes along. I think if I had used grey front that it would have been more consistent. As I play with this down the road, I think it worth my while to lower the rear of the shock and use .45 front springs. As I said in earlier posts, I think there is a difference in the carpets we both run on and this later idea might help in my case.

I also had setup an Altered Ego with the battery transverse. It was really good and very close to this inline setup. This one did use the lowered shock and the .45 springs, so I have some experience with that. We have a lot of 180 corners on our layouts so it will be good to see if the transverse battery or the .45 springs will be the best approach.

Overall, both these car setups are really good and can be the ticket on low to medium bite that are experienced at club racing each week. Your insights and instincts have been proven.

Hi John. A conversion kit was offered and still available on the CRC website. Use p/n 3226 in the search button. It is listed there for $65. Hope that helps.

You will need side links too.

The correct side links are in the conversion kit.

Question Wiita
What does running the Xti rear pod and top plate to a Altered Ego main chassis do?

It gives you a shorter car, 8mm. This transitions on the track to a car that works more like the Gen XL and the Xi did. The car can be ran Long/Short, Short/Short, or Short/Long. Altered Ego is Short/Long, Xti is Long/Short, the AE with the Xti pod is Short/Short. Wiita feels as if the Short/Short car is the best option for on the track performance, it produces a car that is a bit more reactive then the longer cars.
