Pirellis to Bridgestones

Does anyone happen to know the heights of Bridgestones vs. Pirellis 120/180 dot's? Was wanting to switch and wondering what it will do to the geometry. Thanks

 

Lower the front 3 mil

 

Tire size difference is insignificant

I made the switch this year and the tires measure within a 6mm on the circumference, so the height difference is insignificant. I did not change a click on my suspension or ride height. I ran VIR over the weekend for the first time and the 'Stones worked great, had a personal best lap time by 1.5 seconds. BTW, thanks to Stickboy for the hookup on the tires.

WERA Novice #610

Raise the rear one thread on your shock.

 

i went 5mm on my old r6 and new had issues. keep in mind i'm old and slow, but i seem o be able to 'feel" more with the b'stones. plus i like their red hats better....

 

P= 601/641 (Diablo Supercorsa)

B= 600/640

 

i didn't change anything as I measured them basically the same (see post above)

 

I think the biggest difference is a stiffer carcass on the Bridgestones. I didnt have any grip issues..used the YDC slicks, but they get used quick....but was getting some front end chatter in the 10 area and the turn 2-3 area which I never had before. These are both higher speed lefts and really the only spot I had issues. Was kinda bad, considering I really couldnt hammer it in these two areas. Used to go through there full throttle. Cant say if it was suspension, the track or the carcass being harder on the stones. What I do know is I have to figure it out

 

That's right.

Sorry I didn't take time to read the whole post earlier or I would have seen the swizes.

 

Per Mike F (Thermosman): Add 2psi to the front; 32 psi hot on the warmers. It worked for me at Jennings.

 

PM'd ya

 

hope you plan on sharing that info, sean

 

You know I will for a box of Samoa's Try to pit near us at Summit...should be the Lake and Arnie and Charlie again.

 

Damn. I can't pit with you guys anymore???

 

done! the bigger problem for me was spinning the rear (on the SV, no less). the whole time i was thinking it was a pressure issue, but now i'm wondering if it's suspension. would the stiffer carcass require you to back off on the compression a bit? could too much compression damping be causing the front end chatter as well?

 

I am eyeballing this thread very meticulously. Im in the market to switch from Pirellis to Stones also. Sounds as if they perform damn near the same and about $80 less.

I was awe struck when my DOT”s hit me for $390 and the Slicks @ $430.
ok don’t mind me, I’m watching.

 

I'm making the switch.... for the same reasons stated above.

 

I made the switch this weekend. I was having trouble running wide in the Solo so for the sprints I took a little preload out of the front and added a little to the rear to keep from adjusting ride height. I'm not sure it was the adjustments or just me but it was fine for the sprints. I ran a personal best (I should mention that I am not that fast to start with). I have a friends Gixxer in the garage with the Pirelli SC's. I am going to take some measurements. I'll post them up when I do.

 

Hey Sean, if you figure out the settings mind sharing them with me? I had some major chatter too, was running them 30/28 on the warmers for 40minutes. Happened a lot in T1 and T11 at Jennings, I'd let off the throttle a bit to tighten up the lines and it'd get to skipping. Stickboy had mentioned if I got it to take some compression out, so I softened it up two clicks and that made it worse. So I went back to where i was on the Pirellis and left it there.

 

Then go two clicks harder
