Stew, for starters, I would follow the LWT kit instructions regarding spacers on the camber links, the roll centres change front and rear with the LWT suspension on.
Baring that, try running your car as it is. I belive hole 3 (middle hole, 3 hole side) on the arms is close to the 2 hole on the std ones. Personally I used to run them on 2 (outer, 2 hole side), but with 26mm wheels (ie the BIWS spec wheel and tyres) they rub slightly, so I put it back to the 3 hole.
Are you going to be at the next BIWS round? I think i might put the LWT on the car for that, seems to me that the surface behaves more like asphalt than carpet (it's an indoor running track btw to everyone else). I'm deffiently going to be using the Spool though
JC/Tiggerz, i don't believe there is any difference between the two. not on the front anyway.
Anyway, I did some testing last night, and the only thing I changed was the position of the front shock on the tower. This was indoor on carpet, using a spool, and rubber tyres, with 27t stock.
I started from my base setup for the spool (using std arms). basically it means everything pretty much as stock, bar a few changes:
no spacers under rear suspension blocks
0.5mm under the front/front sus. block
C/A (f/r) combination on the front.
C/D (f/r) combination on the rear.
Blue springs all round
No roll bars
50Wt oil, with 3 hole pistons.
Droop at #4, F and R
1.5deg Camber all round
0deg front toe.
Shock's outer hole F and R in arms
Shocks in position 4 on R tower, 3 on front
Pleas ebear in mind the results aren't anything special, i got bunged in heat 2, with 9 other cars with a big range of abilities....Oh and BTW it was only 4 min races, due to the time avaliable vs number of racers
First run, car handled really well, turned in sharp, with plenty of mid turn. occasionally, if i over cooked it into a turn and had to back off sharp, the rear would get a little too loose, losing time, but apart from that a good starting point. result (from Heat 2) 19 laps in 241.20, Fastest lap 10.45, Avg 13.30 (stood as FTD until Heat 5...), 15th O/A
For the next round I put the shocks down to positon 2 on the tower, and the difference was quite prenounced, with very lazy turn-in, but oddles of mid turn grip. It made it (for me anyway) very tricky to drive as the rear was stepping out a too far, too regularly, particulary noticeable at the hairpin at the end of the straight. Somehow I still managed to improve, but I have feeling this may have been more down to the track rubbering in. Result 19 in 240.33, fastest 10.75, average 12.99 25th O/A
For the final Q run, I put the shocks up to hole 4, and instantly found the car much easier to drive, with sharper turn in than the base, whilst still being plenty adjustable in the corner. it was pretty much viceless, had to really overcook it into the turn to make the back step out. However didn't have any luck, got taken out by a back marker whilst putting in some storming early laps (prediciton gave a 21/22 lapper), and a shock popped off. Result 10 in... well i won't bother. I did check the lap times though, still pulled off a couple of tens, and the consistency was much much better (about 1.5s if that).
That unfortuantly only got me in the D-final, but at least i was on pole, so had a chance. For the final, i kept the shocks on 4, as I felt it needed more time to make a decision. Anyway, I easily won the final, with a time of 21 in 242...
Still made a few mistakes, and not helped by one back marker consistantly wanting to race me when i came to lap him....
still a 22 was on the cards, not bad when the A was Q'd and won with a 24 lapper (at least i belive it was). BTW a 22 would got me into the B... I think
So quick summary
Position 2, Lots of mid corner grip, but poor turn in, Hard to drive fast
Position 4, Quick turn in, with reasonable mid turn, easy to drive
position 3, middle ground, between the two.
I have to admit it was enjoyable evening, even considering i wasn't concentrating too hard on racing, and more on the setup. deffiently helped sort my shock positon confusion out in my head. I think the next thing to try would be trying a harder front spring with shock in position 2, and see what that yeilds...
