Does anyone happen to know of a shop that has a 2013 or 2014 aluminum chassis? I'm running my 2013 in usgt so I can use the extra weight, plus my local track is going to the black carpet so it might be fun to play with.

bd7 2015 anti squat settings default
the rear has by default 2.0 FR and 6.5 RR on the arms so assume 3.5 Anti dive squat?. in the parts section the Rear suspension arms options are 41.3 ,42.0mm and 45mm
I'm trying to reduce rear squat on power, which suspension arm options can I upgrade to help reduce this further.
thanks

In the weekend, I struggled to find enough traction on black ets carpet, which is medium traction and where all the xray guys were creating enough. Then I realised the driveshafts are angled a lot even in the highest diff cam position compared to xray. Can anyone tell me the affect of the driveshaft angles?

Less top deck screws seems to be an easy way to gain grip

To a point. This is the only thing about the '16 BD7 I don't care for...pretty extreme halfshaft angles at ride height. You induce even more severe angles during cornering which can lead to significant output speed loss. Severe angles reduce the efficiency of the CV joint (which is sinusoidal, with 100% efficiency at zero angle, and max operating angle usually in the 15-20 deg range). DCJs have higher max operating angles, but the very nature of fitting a DCJ into a fixed hub package increases operating angles (since you have a shorter bone). Have you tried DCJs in the rear?

Freed the rear end up mid corner, with a slight loss of stability on power
That was with a GT 17.5 setup
Higher angle CV, may increase grip, and stability, with a slight loss to efficiency ?
With a Hi diff position, the chassis roll was too extreme for our track

Shock positions:inner 2nd hole mm450 shock oils, 3mm inner 1mm outer upper link shims, 5k diff, 5.8-4.8 downstops, 5-5.2 ride height, 2degrees camber, ff4.2 fr3.5 rf 2 rr6.4 susp holders, short front wheelbase, standart rear wheelbase 0 bumpsteer 0 ackerman, standart rollbars and high diff cam positions, removed motor mounts upper deck screw.
Used volante tires and schumacher sxt3.0 additive.
Car was terrible with x braces, then I removed and was better and put the shocks from 3rd hole to 2nd and better, but still was very hard to drive. It just couldnt create any side grip. Also tried different sauces and xray front2.5-2.8 rear 2.7 springs but nothing.
wondering what would happen if I had put the diffs in low position.

İ am running stock and also tried kit silvers but xrays just give more front bite under hard braking, we had a hairpin at the end of straight so preferred 2.5-2-8s.
