Peter, I broke down finally

TRAKCAR

NICE!!
Congrats, when’s the first track day?

In your neck of the woods, driving Munich to Croatia tomorrow but I’ll be back in Sebring the 19th.

TRAKCAR

Lizards' first day at Sebring.
We had a fantastic day, organized by Orbit Racing, it was hot, about 90F but a strong breeze, humidity was bearable and of course most importantly, Windows UP!!
The car sound just perfect with the windows closed and the SOUL side muffler delete pipes installed, sound up (Guest driver Aalencar):

The whole car is wrapped in new XPEL super thick 1mm clearbra and in all the hard impact areas double up.
Awesome job done by The Film Factory. Nicest wrap job I’ve ever seen. Picking up Mr Purple today with a fresh wrap to live out it’s retirement as my daily driver.

I've tried one session with Dunlop's and verified what we already knew, the tires are probably a full second faster then the MPSC2's after the 4th lap.
Also the Dunlop's aren't as finicky with the tire pressures to make them work.

My first laps, driving like **** (Jet lagged and last time at Sebring was January) were all 2:16's on Dunlops with a lot of understeer out of T16 and T17.
After changed the sway bar front to full soft, I managed the same time on the MPSC2 but only the first few laps and it would have been easy 2:15 on the Dunlops, my TBL was a 2:157.

Normally you change the sway bar at the other end, but because the spring rate in the rear is too much for Sebring in T17 and T1 in soft setting I figures I soften the front bar instead of stiffening the rear bar.
I ran the suspension in soft all day, didn't feel the need to try even stiffer but some fast drivers hit the button to soft before T17 and back to stiffer after T1. I'll try it one day.

At the end of the day usually the track slows 2 seconds and I still managed a 2:17 flat with passenger.
Both the MPSC2 and the Dunlops had 3 days on them, so I think the car on a cold day and me getting my **** together on new Dunlops its a sub 2:14 car. Stock. Crazy.
My personal best with stock .1RS on MPSC1 was a 2:158.

This RS is even easier to drive (And overdrive) but its a lot of fun! Cant wait to go back on fresh Dunlops on a cold winter morning :-)

Great stuff and good to hear about the Dunlop love. They are the better tire now once you get used to the softer sidewall.

I need to fedex my car to Florida. Curious how much the wrap was?

EST

Which are the recommended pressures for Dunlop tires ? Same as Cup2's ?

9972RS

why is there such a price difference between the Dunlop Maxx Race 1 and 2? The Race 1's are 50% cheaper. Are they that bad?

A/S

After 9 months running my rear bar at full stiff (full soft and one side at soft produced slower laps), I finally found speed running the rear bar at full soft by playing with the shocks tuning (DSC).

Randy Pobst was right about the rear sway bar setting, the last delivery of GT2RS in USA came with the rear bar at full soft instead of full stiff.

Front bar is full soft in my car. Adjusting one corner only makes a huge difference, even though the GT3RS front bar is 50% softer than the 991.2 GT3 front bar.

What I'm having problems with is to control the rear on bumpy tracks/roads, I'm still tuning my maps in the DSC. My rain tune seems to work well on bumpy roads (wish DSC had a wifi update capability).

So, it is official: The fastest GT car around Sebring still is a 991.1 GT3RS!!! sorry 991 GT2RS and 991.2 GT3RS owners, you have proven slower around Sebring.

TRAKCAR

And the softer sidewall may even soften up the suspension a bit for Sebring

You should send the car regardless :-)


About $6000 of the top of my head, but extremely well done: http://www.tfaboca.com/

TRAKCAR

Consensus seems to be 3PSI higher.

For me hot:

MPSC2 29F 32R
DSM 2 32F 35R

TRAKCAR

Yes. Original Dunlops unusable, fell apart.
DSM2, better then any other alternative.

EST

Thanks for the info!
You say that Dunlop 2 is a very good tire, have you tried also Cup R ?

TRAKCAR

I can’t afford a $3500 set that lasts less then a day and tries to kill you at the first raindrop.
For that I have a set of 19” with $500 take off slicks.

Soul Performance

Looking and sounding good Peter! Could you send me over that raw video? I would love to have more videos of just side muffler bypass pipes in action. I'm impressed those Dunlops are outperforming the Cup2s, I appreciate the insight.

Indeed a great day. Loaner lizard saved me from misery after my pad gave up on me!
