A Look Inside – K&N’s Super Unlimited Infiniti G35 Circuit Battle Slayer

by Mike Kojima

We have been witness this year to the sheer power and speed of the K&N Infiniti G35 driven by Paul Brown, which is currently tied for second place in Redline’s Pro Track Challenge.  What is unusual about this G35 is that it is a corporate car owned and constructed by K&N as an in house engineering effort.  Usually cars like this are regulated to dressing up the floor at the SEMA show then making rounds at car shows but in K&N’s case it is heartening to see the car out on the track kicking ass and taking names!

What is inside this winning car?  Follow us and let’s take a close look inside.  The heart of any competitive track car is the suspension and the K&N G35 has the right stuff.  Remote reservoir JRZ 2-way motor sports shocks fitted with Eibach ERS race springs have independent adjustment of compression and rebound damping.  There is a reason why JRZ’s are becoming more common in Time Attack and road racing, they flat out work well.

In this view of the rear suspension you can see the K&N in house built suspension links giving full adjustability, the Speedway Engineering tubular racing swaybars and the K&N modified subframe with adjustable roll center.  The rear roll center and camber curve are adjusted by moving the lower link pivot into one of these three holes.

Tubular Speedway engineering race type sway bars are used on the front and rear of the car.  These bars are highly adjustable and the center torsion tubes can be switched out with ones of different wall thickness for even more tuning flexibility.  Stillen adjustable front upper arms are used to provide camber adjustment while all of the rear multiple suspension links have been replaced with K&N in house fabricated spherical bearing equipped custom modified links to get rid of slop and to allow greater adjustability.
