FR-S vs S2000

That little worse balance(the Renesis weighs almost exactly the same as the MZR) would have been a fair trade for a vehicle that has trash for resell value. A '04 RX-8 GT is worth the same or less than a base '04 MX-5. Brilliant idea though but the implementation wasn't good and that isn't the chassis' fault.

The S2000 still had good balance and had an "inferior" piston 4 banger. So I'd say the placement is just marketing fluff. An interesting anecdote is that the two share a transmission design and it's probably one of the more common failures that the two share. :-/

They also share the most retarded highway cruising gearing ever conceived for any <3L displacement engines (I think?)

When you're "cornering" at 120+mph (S2ks with big wings are doing 130-135mph) the BRZ/FR-S is quite "planted". The rearend is significantly more stable than the base S2k. Even the CR will feel somewhat floaty, but that rear wing does keep the rearend a little more tame. I drove a base 08 AP2 prior to the BRZ and hit about 125mph+ before the turn. The moment I added a few degrees of angle, the car's rearend felt very floaty and there were noticeable corrections needed to be made with the steering. Since I didn't want to risk crashing someone's car, I decided to go 50% throttle instead of 100%. This dropped the speed down to about 115-120mph and did not feel very confident.

From that experience, I knew straight off the bat the aero on the BRZ/FR-S was significantly better than the S. The car still produces lift, but definitely not in the same order of magnitude that the S2 does.

I was hitting 125 when you were in the car. I was hitting 128 when I went solo

Some data points for the others in the thread.

I won my class in S2k Challenge with an "undermodded" car. S2k CR with wheels, tires (RS3), exhaust, and tune. The S2k was hitting a Vmax of 128 entering Turn 1. Exiting Turn 2, I am able to hit 132-133 before I have to brake for T3. The S2k enters the front straight at about 88-89 mph. I dare say that I am driving the car at 99% of the limit, especially considering how non-technical this track is.

The BRZ hit a Vmax of 128 entering Turn 1. However, the car lacks the power to push through in 6th gear, so I have to sit near the limiter in 5th. It also scrubs more speed due to the rear not being pushed forward, even at WOT through Turn 1/2. I exit 2 at 125, and never get past 128 before having to brake for T3. The BRZ enters the front straight at 83-84 mph.

The BRZ is at about a 55hp disadvantage, but is able to accelerate up to the same Vmax in the same distance, while starting at a lower speed. The car is slips through the air far better than the s2k, which I originally speculated months ago. Both the CR and BRZ have been dynoed.

The BRZ does create rear lift at speed, so it doesn't completely address the S2k's aero flaws...

Hello Mike!

Don't listen to them. I never understood why 99% of the people are saying the back seats are useless. I'm 6'2, and I put 2 fine ladies at the back without any complaints from them. The backseats are definitely usable. Hope you enjoy the car!

Don't know...

I tried to put two of my kids in a brz at the dealer - one couldn't squeeze his legs in the back seat - he's only 6.

Wife saw that and grimaced... my hopes of buying this car is fleeting fast!!! A couple of more inches...

I'm only 5'7", and I can promise that NOBODY will be sitting behind me unless they don't have legs...

So, what was dynoresult for both cars?

Both are SAE corrected on a dynojet. S2k has a J's 70RR and tune.

No worries at all. Believe me, I have A LOT to learn.

On another note, I took the track s2k to the autocross. Lots of fun!!! Can't wait to try out an FR-S!!

Thanks Mike. Wow, nice numbers from SK2!

Nice view of the new Giants stadium in the video.
