Yeah I hear you, I think its very luck of the draw.

Ill still give your car a once over on Sunday morning, I probably wont get a chance to install the alloy pivot balls you have for me beforehand.

I'm actually thinking of coming down on Friday to get some practice/setup time in, just depends on how much I get done today as I'll be in Newcastle tomorrow, so if I make it I can give them to you.

Dont forget to order the exotek upper arms to compete the build. I would also get a 2nd set of v2 shocks to replace the garbage damper tubes the ifs set comes with. To mount the shocks you'll need to place them on the front of the arm with a few extra spacers on the tower.

Getting ready to place my order, so seeing what all spares I should keep on hand since my track doesn't carry SJ parts. I know I am getting some of the alloy parts and spare a-arms and rear axle is a given.

Any other spares?
I am taking it I can just use other brand ball-studs and ball-cups if needed?
Anyone try one of the SJ brand bodies?

I think you have it covered..not much to an f1 car...maybe get some carbon reinforced hubs and some king pins and the rear spring set for setups.

others have covered the ballstud/ballcup thing and looks like they are prity universal.

I got the SJ body and very happy with it..theres no cutouts for front arms so just be carful here but its nicely detailed and cheap and comes with 2x diff noses plus helmet. I also got the rear diffuser .

Default EXotek front IFS

Built my SJF with an Exotek front IFS Feels Really Smooth. Used the Type 1 Shocks for the front. Very Happy with the outcome

Well I finally got to run the car today, things didn't start off too well with the car wanting to swap ends if I went anywhere near the brake before the turn.
To make matters worse it bounced & skipped over any bumps on the track surface making it unstable & almost impossible to drive.
I was almost ready to give up on it there and then, trying to drive a car out of the box that had horrible handling, and with the memory of the terrible build still fresh in my mind, I had the ebay app open on my phone ready to sell it off for what ever I could get for it.

But......

A friend who had also been watching it, suggested a different weight oil in the shocks to address the skipping issue, and after changing the oil the car was a little better to drive. So what next? my thought turned to spring rates, and decided to try the medium soft springs, the result was also an improvement in handling, but still very nervous going into the turn, and quick corrections of opposite lock was needed.

The next 2 changes also improved the cars handling, one of them I just thought of doing for "shits & giggles" being reducing the amount force of brake in the esc from 75% to 67%. The other change was going 1 tooth less on the pinion gear as it was a very warm day and the motor was coming off very hot after the practice sessions.
After those changes, the car transformed into something that was very fast, very smooth, and had handling that almost resembled a touring car with the same motor (21.5t).
During further practice runs the lap times came down to the point that I was demoralizing some of the 21.5 touring car drivers, by not only catching them, but also passing them on the outside, & turning into the corners faster than they could.

Later in the day I had the chance to pace my car against evochick's, and 2 things were very apparent from having the battery mounted up front.
The first was that my car was "pushing" out of the tighter turns which meant my exit speed was slower, and the second was that evochick was able to get on the power quicker out of the tighter turns with having the extra weight over the back wheels.
The front to back balancing point on the 2 cars were not much, but the result was greater, so before the race meeting on Sunday, I'll be swapping the battery to the back, and the esc up towards the front of the car.

At the end of the day I was a much happier person, because I felt less like I had wasted my money on a car that I perceived was bad. One thing I did notice as the handling of the car improved, is that I had to be more "aggressive" with my driving style because it improved when I did so. Sure, it's not perfect, but I doubt any car is, and my driving is very far from perfect too, but now I feel confident it will improve when I make the changes to it, and that it will be even better with the bladder shocks (when I can get them).

Another point I want to share is that the car took some very hard hits today, including getting the front wing wedged under a bolted down metal track barrier, which took the use of a crowbar to get it free and nothing broke, which is always a good thing so there is a degree of durability in the car.

So, hopefully the racing gods will be kind to us come Sunday, and I'll be able to keep up with evochick to make it a 1 & 2 for Street Jam on the day in the F1 class.

Regards
Rob.

what type of screw did you use to fix the droop screw/chassis issue? I can see it has a wider head on it.

Hi! This is brilliant!

I was planning to do the same, but I was unsure about how to do it!

Which are the parts needed? Could you please explain a bit how did you do it?

Thank you very much in advance!

Just added a 3mm flange nut to the bottom of the droop screw

Cool! Didn't you need to drill some extra hole in the chassis?

Which are the parts you used?

Two holes can be drilled for the servo mounts but chose to shoe goo the servo in place. Used some spacers for the oil dampers, a 0.5mm washer in the arms was needed. Exotek IFS and upper arm kits and 2 flange nuts and some spacers were used.
