Mazda FC RX-7 — An­drew Red­ward (Pro)

NZ Performance Car - - Demon Energy D1nz -

Mak­ing his re­turn to D1 this sea­son, Cal­i­for­nian-turned-Kiwi An­drew Red­ward has shown up with his out-of-the-box beach-vibe FC. Run­ning C’s Garage 555 knuck­les, An­drew has de­vel­oped his own cus­tom lower con­trol arms (LCAs) to suit, which are based off the fac­tory ex­am­ples that have been boxed and ex­tended with big­ger steel plates on the ball joints for strength. He has also used in­ner rack spac­ers to en­sure it gets full travel, and tin­kered with a lot of the MacPherson com­po­nents.

“It used to rely a lot on the cam­ber at the top to make all the ad­just­ments, it changed the KPI [king pin in­cli­na­tion] and would get a lot of wheel flop. I brought all [of] that right out and made all the cam­ber ad­just at the hub, which means the wheels are turn­ing at a bet­ter pivot angle, giv­ing bet­ter trac­tion, and bet­ter lock.” It doesn’t run much Ack­er­mann in it, but he was quick to tell us it’s def­i­nitely not a neg­a­tive Ack­er­mann set-up. Keeper springs have been in­stalled in the front OZ Rac­ing coilovers af­ter droop­ing every­thing down and mea­sur­ing it out on full bump, where the wheel gets a lot more travel — im­ped­ing the front grip on lock — so that it’s not trail­ing around and is ac­tu­ally do­ing what it’s meant to be. The rear has had the same done to avoid hit­ting the bump stop and los­ing trac­tion on big bumps.

“There’s not much you can do in the way of the rear, so we run Parts Shop Max arms for bet­ter align­ment.” he said. There are no sway bars front or rear, as the front sim­ply doesn’t fit, oth­er­wise he would test it, and the rear’s been turfed at the ad­vice of oth­ers. De­pend­ing on the track, he will ad­just the rear bump be­tween hard and soft, with smooth tracks be­ing dialled in harder, and bumpier tracks — like Tau­ranga and Rod Millen’s Ha­hei drive­way — be­ing set softer.
