Since the stock setup runs ff 2.0 and fr 1.0 this makes the arm sweep back a little, where Marks setup would actually bring the arm forward? or less sweep back but actually sweep forward. I would guess he was trying to get some of the aggressiveness out of the front end of the car, maybe a little bit of a push, with the compensation of getting a little more rear traction out of the setup. Going to the 1/1.5 instead of 2/2.5 was probably used so the car still felt a little more reactive to steering change but not enough to make the car feel slow to steering change.
All wild speculation on my part, but thats how I would use that option setup. For asphalt I think this may be the answer to lite feeling in the rear cars.
Of course, not to forget that changing the arm sweep will also effect several other settings on the car, such as wheel base, ackerman, the feel of the shocks due to shock angle and so on and so on.

Gary or anyone else for that matter, Have you played with track width on the 411 at all? I was looking for some more stability as my car was a bit tippy when riding the kerbs in heavy traffic. I am now running the 2.5ff/2.0fr and 1.0rf/3.5rr suspension blocks and really like how this feels. We have not had a hot race day recently so the track has been slower than normal and im not sure if im going in the right direction.

I purchased a set of acer ceramics to install since I am going through my car for maintenance. The bearings for the steering assembly are not flanged and the bearings from serpent are. Any foreseeable problems running the flange-less bearings? Oh and of course the dcj's I ordered come with a completely new bearing size.

The car is quite stable and doesnt feel unsettled. It does feel like the car wants to go up on two wheels and tip over on this one particular hairpin. I have come into this problem when the weather has been cooler and I am wondering if ive gotten it wrong with the spring change ive made. When it was hot I ran green/black or black/grey springs with 500/400 oil and the car was fine. Now its cooler im running grey/white with the same 500/400 oil.

With regards to track width, the best combination I have found so far is 1.5/1.0 front and 0/3.0-3.5 rear, sometimes adding .5mm sheel shims to the rear in low bite. I was running 2.5/2.0 front and the steering felt inconsistent. Narrowing the front smoothed the steering out everywhere (15lb springs front and back). I measured my widths at the ends of the axles, and I think it came to 188mm front/185m rear (?).

I actually ran this on carpet for the past couple of months in stock and mod. I've only had the chance to run asphalt once so far, but I used the exact same setup except for switching to the Mazdaspeed 6. The front dug a bit much but otherwise it drove great..... The only change I am going to make from there is stiffer springs all around. I don't have HPI silvers (the go-to asphalt spring it seems), but I did pick up XRAY 3.0 and 2.6 that have worked well on other cars.

I made a quick change in between heats and lowered my inboard rear camber link to 1mm not remembering that the screw will protrude to far down through the shocktower mount and into the blades on the cvd. Needless to say I did a number on the blades but managed to finish the heat.
A friendly reminder when making roll center adjustments 1mm= bad

They are on route as we speak, also the V2 diff, and a couple other goodies, I'll post results of tests as I get through the items.
I can tell you the Exotec chassis and steering brace are very nice items, although not earth shattering faster it gives the car a more consistent overall feel, maybe slightly better rear grip, although I did end up moving my rear shock angle one hole when I went from the stock chassis to the Exo. The Steering brace, I noticed no difference in performance, but I'm sure its not hurting the cars performance. I do like the extra cutouts for the motor cooling and it seems to be easier to access the pinion set screw. The larger cutouts for the diffs and belt clearance is nice as well, and the slightly extra material off the back suspension brace is nice as well. The stock chassis really had very little material back there. Probably the only thing I don't like about the chassis is that you can't use the stock battery retainers and the tape holders. The screw mounting points are closer together so they have their own proprietory items which make holding the batteries in the old way with a complete loop of tape around the batteries. If I was comparing all the chassis I feel this chassis falls between the 2.0 and the 2.25 stock chassis for feel. I never did get a good feel for the super flex top plate and prefer the cut stock top plate. I hope to get some tests in on the 1.75 top plate and see where that one falls into the mix.
