ZR8ED Posted December 6, 2002 Share Posted December 6, 2002 I'm a believer of the Victoracer 700's. I run them on my VG30ET 280Z. 265/46/16's. respectable in the wet..(not rain) Wickedly sticky in the handling department.. The car just wants to turn faster and faster. It ate up corners at a startleing rate, and even ate up my mistakes. Now I'm a long way from taking on Micheal Andretti, but I do have plenty of training and practice under my belt, and know how to drive my Z on a track, and can push the car near its limits. I'm a bit concerned about tire wear, but over the summer, and lots of tire melting launches and demonstrations, they still look pretty much new. 4/32 tread depth I think.. It was my only solution for traction in a WIDE low profile tire 16" (widest you can buy for a 16" rim..) Quote Link to comment Share on other sites More sharing options...

The added weight is enough to make in uncompetitive. 400-500 extra pounds, heck why not just buy another car and race it, ya know? Wait and watch for 70-73 cars if you like, I'm waiting/watching for a 72-73 specifically. Heavier by a tad than 70-71 but they have a rear end placement issue.

From what I have heard, this is correct - just avoid rain like the PLAUGE. If you hit rain drive slooooooooooooooooooow and stay off the freeway, or else park it.

Guest Anonymous Posted December 6, 2002 Share Posted December 6, 2002 HEY KATMAN that car you were talking about at the begining of this post you said you pull 1.4g on turn 6 (remember) Is that a full race car with a tube frame, cage, and huge fender flares and 12in wide tires or is it only mildly built with normal 7/8in wide rubbers and a small cage??? If you have a web site on that car I would love to see it so I dont have to keep asking you stupid **** about it Quote Link to comment Share on other sites More sharing options...
pparaska Posted December 8, 2002 Share Posted December 8, 2002 Hmm. I'm still on the fence. Potenza SO3s or maybe Victoracers. I'll probably just go with the S03s since I know them to last a bit. Thanks for the pointers though guys! Quote Link to comment Share on other sites More sharing options...
G Gress Posted December 8, 2002 Share Posted December 8, 2002 Question for you V-8 guys. Thinking about running 275-40 17s on the rear, for the best handling should I run the same on the front also or go smaller in the front. BTW I realize I will need flares Quote Link to comment Share on other sites More sharing options...
johnc Posted December 9, 2002 Share Posted December 9, 2002 You'll need to do a bunch of suspension work to get the most out of those tires. Until then, size doesn't matter... Quote Link to comment Share on other sites More sharing options...
G Gress Posted December 9, 2002 Share Posted December 9, 2002 John I plan on a bunch of suspension work. Want to build a car around the tires, but need to start with the right size tires in the first place. I'm not lost around suspension setups, but most of my experience is with circle cars, same size tires mandated all around. Thanks Quote Link to comment Share on other sites More sharing options...
Nismo280zEd Posted December 9, 2002 Share Posted December 9, 2002 yeah well after you strip out the interior and put on some aluminuim alloys the 280's are pretty quick.. not to mention they have the added benefit of EFI. Quote Link to comment Share on other sites More sharing options...
pparaska Posted December 9, 2002 Share Posted December 9, 2002 I'm wishing I'd gone with 16x8s all the way around and be able to run a 55 series tire. The sidewall on the 255/45-17s are too stiff and hurt straight line traction. I'll keep them though, but think about this when selecting wheels.

Or, Keith, has he hit the 200 mark? Real east coast SAE calibrated 203. I never thought I'd see it in an ITS motor. A couple years ago we discovered something in the header configuration and it took until this year's ARRC rebuilds to figure out how to match the carb side of the equation. As usual, Sunbelt persued the science, not the smoke and mirrors. Kudos to Jim. Quote Link to comment Share on other sites More sharing options...

If you have a web site on that car I would love to see it so I dont have to keep asking you stupid **** about it Like johnc said, typical ITS 240Z. No flares. 8 point SCCA cage, 14x7 wheels, 225-50 Hoosier S03 rubbers, 400/350 spring rates, 5-1/4 inches at the rockers, and SERIOUS shock development. Interestingly ITS rules don't allow the cage to pass through the firewall, so just a strut bar up front. Sorry, no website. Quote Link to comment Share on other sites More sharing options...
johnc Posted December 9, 2002 Share Posted December 9, 2002 > Real east coast SAE calibrated 203. Tell Jim congratulations. Looks like the Z will be competitive for another 5 years. Quote Link to comment Share on other sites More sharing options...
johnc Posted December 9, 2002 Share Posted December 9, 2002 Regarding the 275/40-17 tires from a handling perspective... When you get below a 50 series tire on a 240Z (or any car really) you are transferring some of the compliance requirements that the tire took care of (from the sidewalls) to the shock absorbers. Some of this is from the stiffer sidewalls and some from the increased air pressures. A common autocross tire size (265/45-16 or 275/45-16) for the Z really needs a set of double adjustable shocks to make them work better then a set of 225/50-15s. I've seen back to back tests that prove this. Without a more compliant shock package a 45, 40, 35, or 30 series tire will tend to skate across small bumps. In addition, you need to reduce stiction and weight throughout the suspension to allow the shocks to work. Think supple, not stiff. Quote Link to comment Share on other sites More sharing options...
G Gress Posted December 10, 2002 Share Posted December 10, 2002 Thanks John, I know what you are saying, and I would love to run 50-15s, but 225s seem a bit narrow for a relatively light car with 400ft/lbs. torque. Anything wider in a decent tire is impossible to find short of Hoosiers and thats why I'm looking at the 17s. Thanks, Greg Gress Quote Link to comment Share on other sites More sharing options...
