I was drooling over your car that weekend. Great looking setup, and functions well, too.

Hey guys,
Just a few quick questions. I am starting to get more into Time attack and was reading in the thread and a few other places, but is there a reason you guys choose 17s over 18s and also squared over staggered setups? I see a lot of 240s with the staggered 18x9.5/10.5 look and it looks cool, but translating that into racing, I see people saying 17x9.5 squared is the way to go. I understand that 17s are cheaper and can fit more rubber. And running square saves costs because we can rotate them and it helps the car be more predictable, but besides those\reasons, is there any deeper meanings that I'm not fully seeing?

square setup maintains the car's neutral balance. unless you need huge tires out back, square is preferable IMO.

when i first got my 240 years ago i sold the 18s in favour of 17s think there was less unsprung wight and inertia. however, i realize in hindsight that those thing depend on the COMBINATION of wheel and tire. eg. you may loose mass dropping to 17s but gain mass in the tire to maintain the same od. just something to consider.

i believe a lower profile tire=greater performance too. there's an option/hot version video where they test a Z33 with 17s, 18s and 19s and I remember the 19s were fastest around tsukuba.

Found a better way of transporting slicks to the track, much better ride quality to and from the track also.


Front flares finally came in, now I won't have to worry about the slicks rubbing the wheel arc and can lower the front down some more. Just taped in place for now, checking fitment and making doubly sure they are fitted properly before drilling holes.

Figured I would throw a few pics of our setup.
We acquired an 04 G35 Coupe 6spd with Brembos awhile back and have been slowly tinkering with it and putting on parts that we had around the shop to have a fun weekend grip car.

So far it is..
BC Racing DR True Type Coilovers
SPL Front Compression Rod Bushings
SPL Front Lower Arm Inner Bushings
SPL Front Lower Arm Shock Bushings
ISR Differential Bushings
ISR Subframe Bushings
Tein inner/outter tie rods

Stoptech Slotted rotors front/rear
Hawk HP+ Pads front/rear
ISR Stainless Brake lines front/rear
18x10.5 Enkei RPF1 on all 4 corners
Maxxis RC1 275's on all 4 corners.

ISR Resonated Test Pipes
ISR Y-Pipe
ISR Single GT exhaust
Tuned by RS-Enthalpy

Bride seat rail
Recaro Pole Position
Nardi Deep Corn

All in all we have been pretty impressed with how the car has handled, were going to work with the guys at BC to get a bit more grip out of the car now that we pulled some weight out of it and added a bit more power, as well as install some prototype ISR front upper camber arms to be able to play with the alignment more.

After a few track days the 280k mile vlsd finally gave up the ghost so we should be putting a KAAZ 1.5 way Super Q diff in it shortly and getting back out on track

How do you find the HP+ pads in combination with those DOT-R class RC-1 tires? Too little pad or just enough?

I had HP+ pads with cheap UHP tires, and it was too aggressive of a pad for those tires, they would lock up very easily. I felt that moving up to a stickier EXP class tire (RS3, RE71R etc.) would be the perfect combination of pad and tire.

I also know a lot of time attack guys in my area that are using the DTC pads with EXP class tires. I would think that is too much pad for those tires, but they all seem to like the combo. Perhaps they use them for the increased fade resistance.

Would DTC pads, or anything more aggressive, be a better pairing with your DOT-R tires?

Depends on horsepower, speed, and weight. I ran HP+ with some Dunlop StarSpecs....

HP+ were definitely not good enough for the StarSpecs and 300ZX iron calipers and Alu in the rear. I moved to Carbotech XP12 front and XP10 rears. Was a great setup with vents....

So its really hard to say. I was running Infineon, Laguna, and Thunderhill which all have pretty long straigtaways.

The HP+ pads seem to work pretty well, admittedly we kind of threw together the car with stuff we had in stock or used from other cars (The wheels were left over, tires were actually used scrubs, other parts were prototypes sent to test, seat was out of my track car, etc.)

Really it was a super low budget thing just to go out and have some fun in a road race setting. The brakes seem great, I wasnt really trying to push super hard as we had just started shaking the car down, but all in all they seemed pretty well matched. I could stand on the brakes pretty hard and it really didnt lock (Once or twice I got a little bit of lock up, then again tires didnt have a ton of heat at that point), and in the same vain I didnt feel like I had to stand on the brakes a ton to stop the car and I wasnt worried about not having enough brake.

Also its a 275 up front so that is a decent amount of tire to transfer the energy to the ground so Im sure that helps, if it was a 235 or 45 I may not be as confident in braking.

The track we were at was pretty short as well, its a local small road course where top speed down the longest straight is about 100mph, so you can take that into consideration too.

Were going to try to refine it a bit in spare time over the next few months and start to hit a few other courses and see how she does, maybe do a GTA event or two in it once we get some more power and a bit more grip in it and some more seat time.

Impressive set-up of the wires. Great structure as well. Have fun riding it.

We were able to get our KAAZ 1.5 Way Super Q installed, and also a set of prototype longtube headers we got in from ISR and made it out to the track to see how it felt.

Temps were incredibly low (27 degrees in the morning, warming up to about 46 mid day) so getting any sort of heat in the tires took quite awhile, but the diff performed awesome.

It was very predictable and gave us a lot better control compared to the warn out old VLSD.





Were planning on refining the throttle body and intake manifold setup to try to dig out a bit more power out, and then maybe upgrade the cams to some Tomei units and hit the dyno and track again
