Nissan S15 — Mitch Gibbs (Pro-Sport)

NZ Performance Car - - Demon Energy D1nz -

Ar­guably one of the most se­ri­ous cars in the ProS­port field, Mitch’s S15 uses TDP every­thing up front, with some Parts Shop Max pieces down the back. Switch­ing over from a Ce­firo run­ning Parts Shop Max units, he has no­ticed a lot more lock in the new chas­sis, es­pe­cially with the TDP equiv­a­lents.

“There’s so much more ad­just­ment and it’s sim­pler to set up. TDP sup­ply a whole guide of what they rec­om­mend for what you’re try­ing to achieve, and it’s also bet­ter at self-cen­tring, with more Ack­er­mann ad­just­ment.”

With a rec­om­men­da­tion of start­ing at 10mm Ack­er­mann and finding what suits, Mitch’s test­ing has led to the cur­rent set-up with 6mm of Ack­er­mann.

Fol­low­ing a big hit in Dunedin, in which the For­tune Auto front coilovers were dam­aged, BC Reds have been in­stalled as place­hold­ers while new For­tune Auto units are on their way. The orig­i­nal For­tune Auto rears re­main in place, but have been raised slightly. Mitch raised the rear to help get it on the trailer, but dis­cov­ered that it ac­tu­ally helped gen­er­ate a bit of grip on the [class max­i­mum] 235 tyres — help­ful when you’re pump­ing out 521kW (700hp).

The rear has been soft­ened as much as pos­si­ble, run­ning 6kg springs and no sway bar. The rear trac­tion arms have been pulled right for­ward for more for­ward bite, and there is a lot of pos­i­tive cam­ber dialled in to com­pen­sate for power load — when it’s tipped in and power is put down, the rear re­turns to square. Although there is noth­ing spe­cific he would like to change in terms of com­po­nents, he would like to jump to Pro to run a big­ger tyre in pur­suit of more grip.
