Real result at Buttonwilow I atteneded
350Z HR with suspension and tires, 2'02.9
FRS with suspension and tires, 2'05.xx

 

Good to know real world the Z pushes ahead!

I think the OP and friend are still heading to the ring!

 

I dunno if I agree with this. I think the Z with the same supporting mods, the Z would still be faster on this course. My basis for this is my '04 350z Roadster ran a 1:24.5 with RS3's and h & R coilovers with a stupid counter productive hellaflush ride height. This was also done on my second ever track day, so with a real driver and taking into consideration the added weight of the roadster, my money would be on the Z here. I think it would have to be an abnormally tight track, or autocross for the fr s to be faster. I will agree with 2th though and say it is possible, but would really surprise me if it indeed was faster.

 

The driver is the most important part of the lap time comparisons.

 

It'd go something like this?

Double post

 

I drove a BRZ on race tires on our test-and-tune course. I know the course very well, (it has not changed in ~2 years) and also drove my Z on street tires the same day on the same course....

My modestly-prepped (No HP mods at all) BSP Z on street tires, was about .5 seconds faster than the BRZ on race tires. (29.5xx vs 30.1xx)

FWIW, I love the BRZ/FRS.

 

Just out of curiosity, what are the dynamics of the course?

 

This is the course:

(From 3 different points of view)

 

The FR-S is a great platform, one I have considered myself. It's also great bang-for-buck, and with a bit more HP and a capable driver, it can be a super fun and fast track car.

I played with a modified one at Laguna Seca this weekend. This was in the advanced group, so it's not like there was some n00b driving it. It was many seconds slower than my modified Z. Still not apples:apples, but it is real data. I'd say a capable driver in an FR-S compared to an "ok" driver in a 350Z is a very tight comparison on a "big" course.

Pro driver, Randy Pobst, takes a stock BRZ around Laguna for a best 1:51.3 lap time:

 

smartest reply in this entire thread.

 

Evasive Supercharged FR-S with pro driver race tires did 1:59 at Buttonwillow. I have done 2:00.8 at the same track configuration with street tires Rs-3, fully tuned w/cam. I think the power of our Z is still have some advantage over Fr-S. But who knows, time will tell.

 

All depends on the track. SOW may be a different story (with equal tires and drivers)

 

With that guy behind the wheel that Suby looked really good at Laguna! Nice video and of course a novice behind the wheel on that track would be much slower, especially at the corkscrew .

 

I want him to drive my car and/or I want to drive a stock FRS for comparison to the awesome Pobst. He jumps that corkscrew, it's awesome.

 

Both he and Skeen will drive just about anything you want to hand over. See when he is town next time.

 

True, Z sucks on a tight course such as SOW

 

That would be sweet! Jumping that corkscrew would scare the ish out of me!

 

Figured id jump in here. On any track or auto x stock to stock the z wins i proved this in my 05 35th on a very small auto x while i was on conti dws rear tires and him showroom stock. He returned on r888 and gained almost 2 secs. The michilen primacy tires stock for both brz/frs are high mileage tires. Now im in an 08 nismo still on street tires and those danmed conti dws up front but only losing to the frs bye a few tenths ill let yall know how i do on r compounds.

 

Interested in the layout of this autoX course...
