Thread: Is our suspension setup correctly by aftermarket strut MFR's? Is the bias correct?

    I think heavy steering is the only one.

    For some reason the HD only shows up if I post it as a link... It's up now in 1080p.

    Are those tire pieces flying when you take sharp turn? Also I never notice anyone run big camber like puma GTO did. I'm sure puma had their suspension dialed in the best for 3000gt?

    ralliart3000gt said the front has negative 6 degree of camber. crazy.

    even the rear has tons of camber.

    They also ran narrower tires than we do, the narrower the tire, the more camber it needs.

    Yeah, that's tire rubber. Not mine, but just someones on the track. It's what we call marbles. Rolled pieces of rubber coming off of slicks.

    That's exactly right. The Puma GTO guys knew what was up.

    You Sunday driving in that vid, E? Your 5 seconds off your last NASA trial pace. Looks like your slipping a lot on Danny Lesson and turn 11. Were the drivers side tires significantly hotter than the passenger side?

    How did you like the Hawk DTC 70 brake pads? You think I can use them with DOT comps or is that not enough tire?

    Sunday... $100 for all day. You're coming right?

    Im going to do some outside the box stuff this week man. I'm considering ditching the sway bars all together to see what an independent suspension feels like. Apparently its really grippy. I'm going to load up droop and see what happens when I compress a corner and pull the opposing up with the spring. Will be interesting to see if that setup will behave like a sway but keep the grip of an independent suspension and ditch the tire slip penalty of the antiroll at the tire.

    Nah, the car wasn't slipping or anything I was just out testing.(yes, driving like a Nana!) Going deep on occasion (off apex) to throw it in, seeing how much lean I could get out of her. See how much of the suspension I'm using now? I't like hardly 2 inches. You gotta ride in it now! It's good stuff. I also had a small thought about the perches popping the outter ring off and kept that on my mind. (Listening for the BANG! Like what happened to Chumpy) I'm really happy with the way the car performed. I'm sure I can take it well under the 2 minute mark now, if I can get this cooling thing sorted out. I'm flat-bottoming and sealing off the engine bay on Saturday with an .063 aluminum sheet. I still don't have tires on it but I'd like to come and watch everyone play on Sunday. When are you heading out there? Are you runnin'?

    The pads were awesome, but that's my 3rd day on those, I had those on at Nasa last summer. I think the Torque brake fluid is a winner as well but honestly I had changed the fluid, added the brake coolers and the titanium backing plates all at one time so I don't really know what made the biggest difference.

    Currently on a hot track. I've. On my third spring setup. First setup was 600lb springs with a 200 lb 1" from bind. Lap average was 2:09. Fastest lap 2:07. Boiled my ATE Blue brake fluid and lost brakes 100% on literally the last lap. Pedal sank all the way to the floor and no brakes! Holy Fuck! When I pit the front rotors were 800 degrees and the rears were 410. Front tire temps were probed at 160 outer and 148'degrees inner. The rears were 150 outer and 135 inner.2nd session... Springs setup at 600lb front and 600 lb rear. Also swapped the brake fluid out for Motul RBF 600. Lap average was 2:05 was experiencing a lot of Oversteer. Rear wars like mash potatoes and really loose. Pit and noticed I was shouldering rears a bit. Rear tire temps were 165 outer and 150 inner. Fronts were 158 outer and 154 inner. Brakes held, lap average 2:04. Fastest lap 2:03. outbreakThird session...dual springs in rear, single 600 in the front. Tire temps were 157 degrees rear outer and 154 inner. Fronts... 168 outer 163 inner (also about 10 degrees warmer). Lap average 2:02.7. Fastest lap 2:01.9.Gearbox is starting to get noisy and grind third too!
