XRAY - Model racing cars

Well, hasn't it come a long way since my t1

I didn't manage to get used to the car in the run time i had, but, the kit setup was a great starting point and i felt that once i am used to the car, it is far more positive.

I was running the diffs a bit loose to wear them in (kit setup ball diff front and rear)

Got the best lap times with light blue springs front (felt it was diving and scrubbing too much speed)

Other than that it was as basic setup without any weights

I felt the car seemed a little unsettled at times, although i am really not sure as i wasn't used to how different it was. It was however in no way difficult to drive.

I didn't want to change anything drastic from this setup as i was fairly comfortable with it hence just the light blue springs. I also tightened the front diff a bit

This cured most of the low speed off-power oversteer. Its so difficult to explain but by keeping the car at a neutral speed through hairpins i didn't have a problem. When i came in too hot and let off (no braking) the car would switch ends.

Please advise on these thoughts.

Increase dampening at front.
Tighten front diff further (worried that its a low speed pendulum effect) Tony any comment on kit setup with ball diff ?
Anti Dive (use upper hole at front or use lower hole at back)
[If i lower the roll center, later option, will i mostly affect on power grip]
Front antiroll bar options (use one)

Car was great and had brilliant setup out of the box nice one xray

Round of beers goes out to you in the post

To put this in perspective i was doing faster lap times than my old car, with it feeling completely different from the old car...

I'd close one or two holes up front first, then try a harder spring up front. I wouldn't tighten the front diff more than medium though. Are you using tire additive? If so, how are you applying it to each end?

I am using LRP aditive light blue on LRP 24r slicks.

Applied evenly before each race (even application stems from my old car may only do inside front next time, if thats what your leaning toward.

I will double check the diff tightness tonight, however thats all questionable from person to person how tights tight

I did try blue springs up front in the last race but but by then i had a harder spring rear.

let me explain:

Race 1: Kit stock setup (Running diffs in)
Race 2: Light blue front (Medium Front Diff)
Race 3: Blue-Green Rear
Race 4: Blue Front 2 holes closed, Increased rear downstop

I needed a stiffer setup so you will have to excuse race3 didn't have time in race two to up both springs equally as the balance seemed ok in race 1 hence i wanted to raise each equally... As possible

Race 2 was quickest and Race 4 was probably the least dramatic and easier.

I did have too much steering travel set ! So the car maybe ok, i am reluctant to change too much. Its nearly spot on etc
