Hi everyone,
Just another report back from the weekends racing....this time back at Broxtowes astro turf track again.
Last time out here the car was great, and that was in not so favourable TM2 conditions, my set up from then can be found earlier in this thread. This time out however the conditions were near on perfect for the car which meant some alterations to the previous set up were needed.
Although the track was being much dry from the start of practice I opted to start with the setup which had performed so well previously. Within a couple of laps I decided to try a change in tyre from schum. silver staggers/ballistic buggy greens to yellow staggers and schum. yellow mini spikes. I much preferred the balance of the car with this combination but it still felt like the car was pushing through the corners a little. To rectify this I lengthened the rear inner camberlink to the longest position, keeping the hub position on the inside. This made a massive difference and brought the car to life around every part of the track, I've learned that the shortest position really does help in lower grip conditions but when the grip returns it seems to lock the rear end in too much.
Another change I made, after round one I think, was to place some 1.5mm spacers under the front ballstud. Apart from working in tandem with the lengthened rear camberlink to help the car rotate more mid corner I actually did it to make the car feel less aggressive and more predictable on corner entry...this also worked well and was how I ran the car up until the final.
In the open practice before the finals I reverted back to 2 degrees anti-squat to try and get better through the tighter bits, I'm unsure whether it made a massive difference but whilst the grip was available there was no danger of it having an adverse effect on the rear end (to my knowledge!).
At the same time I also went to ballistic buggy whites on the rear. I knew from previous experience that the tyre works well at broxtowe but I changed as the yellows I was using were now struggling to give the forward traction required for me to be able to clear a tricky double jump. In terms of lap times I don't think there is much in it though I think I did prefer the feel of the yellows!
The car was excellent again and I'm really looking forward to trying it out on a different off road track....below is the setup as it ended up : )
Front
40 weight associated oil (ah, that was another change, up from 37.5). Think I may go back to 37.5 though as it feels a bit stiff.
Black losi springs
Kit pistons with two holes drilled to 1.4mm
Outer hole on wishbone
Middle on tower
Longest camber link position + 1.5mm spacers under ball stud
Schumacher yellow cut staggers (low profile)
Rear
27.5 weight associated oil (doh, another change...up from 25 weight, due to higher temperature)
2.2 (red) CoreRC springs (double doh...another change...up from CoreRc whites)
Kit pistons
Drilled inner hole on wishbone (really thinks this helps)
Middle hole on tower
Inner camber link position on hub
Inner position on shock tower
Was all good and will be where I start off for the Broxtowe regional next month
