But if you've seen that be the case, I'm all ears. Personally, I think there's still maybe 2 seconds I can find by smoothing some things out. But I don't think there's 4 seconds. Maybe I'm wrong?
Frankly, if you're telling me it's possible to get within a 1/2 second of the lap record without spending $30k to build a SPB, then that would become the MOST EXPENSIVE half-Second in the HISTORY of half-seconds. haha
This advice is speaking to me this afternoon, along with some of the others here. maybe because it includes some of the direction I've been going anyway: RBF600, GT3 Cooling ducts, water pump & t-stat, UDP, etc etc.
I'm still seeing conflicting opinions on square vs staggered.

In "
similar cars" Yes you can. That means similar wt/hp, tires, and setup. An 03 Box S should be very close on the same tires and a decent setup with some camber in the front. On a long track where you can stretch your legs the 03 should be faster with higher hp. On a tight track with a lot of corners the SPB will have the edge due to better wt/grip. Right now you not in a similar car. You are camber-challenged and leaving a lot of time on the table while shredding the shoulders of your tires. Using ALL of your contact patch needs to be priority one IMO.
My base Cayman is 261 hp and on the same tires runs well with the SPB guys at Fontana, Laguna Seca, and Buttonwillow. They will get me at Chuckwalla and Streets due to tighter tracks and lighter weight. An 03 Box S and 09 Base Cayman turn very similar laps on the same tires and setup so a very good comparison.

I also run the exact same setup street or track. I have alignment checked and corner balanced annually and that is it. Nice even tire wear with no drivability issues at all. I don't know why you would change it unless you were running extreme camber/toe settings.
For reference, the POC historical track record for BSR (SPBOX) at AAA Speedway is Nathan Johnson at 1:55.5 on Toyo RR 40TW tires. Last April I ran a 1:55.2 on RE71r street tires. Boxster Spec track records are well within our reach once we use all of the contact patch.
