The question is whether or not you use TPMS sensor on your track-ONLY wheels?

I'm about to pull the trigger on a tire/wheel package and I'm not sure whether to spring for the extra $350 on something I'll be constantly manually checking away?

Thoughts?

 

it's good to have in case you have a puncture while waiting at the hot pit or while on the track. they're not accurate but at least it'll warn you realtime something's not right. i don't have it on my track wheels. i just check my tires/pressures before and immediately after every session.

 

It is useless IMO. When you deflate your track tires at the start of your day to give room for pressure increase as they get hot on the track, you will always get an alarm sign that you have a flat tire...

Also you will burn a lot of brake pad sensors and they are expensive to replace for something that has NO utility IMO. I got rid of the sensors on my GT3 (sold now).

 

This was in line with what I was thinking. It seem a lot like the brake pad wear indicators that you ziptie to the shock to avoid them constantly being damaged.

 

what does brake pad have to do with tpms?

 

I am just saying that these wear sensors are as useless as TPMS.

 

I wouldn't pay the extra for the tpms and I disconnect the brake pad sensors.

 

x2 - Pressure are so low to start, it's worthless. Plus you don't need a sensor to tell you you have a flat on track, you'll know, ask me how i know!

 

what pressure do you start at with the stock pilot cups?

 

Don't know about the new car but on my 996tt with mspc's I'd start @ 28/29 stone cold. I'd keep them at 40 all the way around hot.

To you experienced guys in GT3's, does that still sound like a reasonable approach?

They have nothing technically to do with each other, I was just drawing a parallel between things that are useful for street that become pointless for at the track.

 

I use TPMS on my BBS E88 wheels with R6s. I love knowing what my tire pressure is during a run. Why would anyone turn down more info if it is out there?

 

Because it is not accurate enough to be useful while on the track. Also you get a alarm signal for a flat tire every time you decrease pressure before going on the track. If you don't experience this, I wonder if you really track your car or if you let pressure increase above where it should be...

 

The Gen2 TPMS (MY10) is far more responsive and accurate.

Gen1 is lousy, terrible
