It is hard to differentiate the cars even road to track cars sometimes.
My AW11 is in a big grey area, it's appears heavily modified, but it's not.
Suspension - The suspension modifications are mainly stiffer springs (3kg/6kg), I'm still using stock replacement Koni Sport shocks and I still run the car at standard suspension heights. No RCA's or fancy replacement suspension links. I run an adjustible sway bar on the front and a recycled SW20 sway bar on the rear.
Engine - The 20V engine conversion looks like a heavy modification on paper, but it's an unopened stock motor with a basic aftermarket ECU. Toan's worked 16V would easily make more power with it's much bigger cams, lightened flywheel, ported head and Autronic ECU.
Brakes - The brakes upgrade is just a combination of stock brakes off bigger cars, ST185 twinpots on the front with non-slotted Corolla 254X25 rotors, SW20 22V calipers rear with a non-slotted AW11 front rotor. It's an improvement in braking power, but mostly in thermal capacity due to larger rotor mass, but it's added 2+kg per corner. It's not like they are $2k worth of Wilwood billet calipers and two piece rotors. The brake pads are cheap $80 TRW Track pads, nothing special like $300+ Ferodo DS2500's or Project Mu HC+
Exterior - The bonnet vent, it's looks like a massive aerodynamic enhancement, but it's just for better cooling (in theory anyway). There are no splitters, under trays or wings.
Interior - I've stripped the carpets out, but still retain factory dash, centre console and door skins. I'm still using a stock recaro bucket seat and seat belt as well.
Weight Reduction - I've ditched the non working AC system, heavy thermo fans, carpets and rear wing. This bring it down to 1060KG, the nearly same weight as a
stock JDM 84 AW11a.
The majority of my modifications could be replicated on a tidy stock looking street car and you'd never know.
