A Question for the more experienced, what pressure should I run front and rear? I currently have the track pressure of 40 rear and 38 front.

I thought I should start around the 26 PSI mark? and go down to 20?

What are your thoughts. I have Toyo T1R's 275/35 x 18.

Thanks in advance

Hey Paul, I am running the same size and pattern tyres. I fournd no differecne between about 38psi all round and 30psi all round...you might as well just leave them at 38.

The lower the pressure the more grip the tyres can handle as the tyre flattens itself out more obviously which is tops for those heavy starts :) .. Paul run the pressure that you stated "26psi"

With 275/35 x 18 I wouldn't bother so much about tyre pressures. Maybe drop them to 28-30psi.

You will drop your time more by snapping your gear changes faster :(

Edit: You will find me at the hotdog stand :)

Yes, The R32 ran a 12.4, it has GTS turbo's. The best I could do was a 12.5. I stuggled to get the power down. I could not get my 60' below 2 sec. I wheel spun using tyre pressures from 40-25psi and did launches at 5, 6 and 7. I did a 7500 prm launch but did not get traction until 3rd gear. My best terminal was 115mph and I got that after having it pop out of first at about 10 ft.

My times were poor, but I had some fun and reside myself and the car to the track.

      Magnetic Drain Plug Snapped in Half

      By kevboost7 · Posted

      Update: I got the magnet out. I bought 3 different flexible magnetic reach tools, but none of them worked. The magnet on the tip was all less than 2lbs of force, so i had to buy a special cylindrical magnet that had a pull force of 9lbs.  The magnet finally came in the mail yesterday, so i got under the car to get to work. The super strong magnet isn't that long, so i only have about 1 finger pinch lengths to hold it. I was so scared when i was going in the hole, that the 9lb magnet would just fly away inside the oil pan never to be seen again, but i had my butt cheeks clenched and finger gripped on that thing so tight, i managed to get it to suck the other magnet out.  It was a victory for me last night.

      New fix for low tyre pressure from bmw

      Yep, pretty much what you said is a good summary. The aftermarket thing just attached to the rim, then has two lines out to valve stems, one to inner wheel, one to outer wheel. Some of the systems even start to air up as you head towards highway speed. IE, you're in the logging tracks, then as speeds increase it knows you're on tarmac and airs up so the driver doesn't even have to remember. I bet the ones that need driver intervention to air up end up seeing a lot more tyre wear from "forest pressures" in use on the highway!

      Anyone know this frontpipe?

      By sunsetR33 · Posted

      Yes, but you need to do these type certifications for tuning parts. That is the absurd part here. Meaning tuning parts are very costly (generally speaking) as well as the technical test documentation for say a turbo swap with more power. It just makes modifying everything crazy expensive and complicated. That bracket has been lost in translation many years ago I assume, it was not there.

      Hahaha, yeah.... not what you'd call a tamper-proof design.... but yes, with the truck setup, the lines are always connected, but typically they sit just inside the plane of the rear metal mudguards, so if you clear the guards you clear the lines as well. Not rogue 4WD tracks with tree branches and bushes everywhere, ready to hook-up an air hose. You can do it externally like a mod, but dedicated setups air-pressurize the undriven hubs, and on driven axles you can do the same thing, or pressurize the axles (lots of designs out there for this idea)... https://www.trtaustralia.com.au/traction-air-cti-system/  for example.... ..the trouble I've got here... wrt the bimmer ad... is the last bit...they don't want to show it spinning, do they.... give all the illusion that things are moving...but no...and what the hell tyre profile is that?...25??? ...far kernel, rims would be dead inside 10klms on most roads around here.... 😃

      You're just describing how type certification works. Personally I would be shocked to discover that catalytic converter is not in the stock mounting position. Is there a bracket on the transfer case holding the catalytic converter and front pipe together? If so, it should be in stock position.
