"...Not gonna go an faster in this car without taking out your wallet..."

Here is a better source of lap records for the various track configurations at UMC. Unfortunately it doesn't tell you the make and model of car in the NASA classes.

Mark's record is from last years PCA club race and he was the only Spec Boxster. Other specs have run in GT4 past years. One big thing missing from the ClubRace site is what configuration was run for the time.

I have TTC records in my base Boxster from when the class existed. Adam Heller's GTS2 times are from an S racecar, as are Bill Noblitt's PTB times.

This great, Max!
So what I'm seeing then, is a LARGE disparity, between SPB (2:19.022) vs the two S racecars you described, GTS2 (2:12.341) and PTB (2:09.677)

I don't know which of those times I'd use as a gauge to compare my own largely-unmodified 'S' to. If I'm comparing my 2:22 to the SPB 2:19, I'm seeing it. If I'm comparing to the 2:12 or 2:09, then I'm gonna throw-in the towel right now.... 'cuz there ain't now way in HELL that -I- (me) can get within a stone's throw of those times with the car I'm driving now, as it is. If somebody else CAN, then yeah.... I'm not so good at this after all, huh? And all 4 of the instructors who've ridden with me this year have simply been blowing up my skirt....

That's a little demoralizing.

I'd say no. Those "S" race cars probably have the same motor but are running R7 tires and are 500lbs lighter. Not a good comparison to a full weight street car on shredded shoulder street tires. From your times I agree with your instructors that you have good driving skill. Now it's time to get your tires and setup in the game.

Perfect! Now that we have a general idea of where you stand, I agree that its time to improve the car.

I'd suggest (as others have) starting with camber (adj LCA), tires (NT-01), and brake pads (EBC Yellow or similar race/street pad). Those will make the biggest difference for the $$ invested.

If you really want to do something about the shocks, springs, and sways, then M030. Otherwise, they can wait because these are fairly big ticket items.

Also, you'll have to make some hard decisions about street drivability and comfort in regards to a racing or sport seat and harnesses vs the stock seats and seatbelts. A sport/racing seat with a 6pt harness will help keep you in the seat about a million times better than the stock seat and seatbelt, but it comes at a cost.

Its a slippery slope...

In my own experience this is where data is helpful once you have a platform that doesn't change every event.

My car is basically a Spec Boxster without a cage and hard top. I had hit a wall at ~2:17/18 on Outer. Careful review of my outings showed a few track sectors where I was lifting when I shouldn't, a corners Vmin was not consistent and much higher on some laps, etc. I applied knowledge of that to my next events.

Now my personal best on Outer is 2:12.8 on A7s and I've run lots 2:14s and 15s on RRs. I ran a 2:16 and change on NT01s last Saturday with the 30-60mph gusts that day. (It was not optimal for setting fast times)

Don't be demoralized. You are right on target.
