Hello,

I am an instructor with Chin Motorsports and was talking to Scott Bartlett recently, who is one of the Chin Event Manager's, and he got to attend a testing at Sebring short course driving both the GT350R and the regular GT350 Track Pack and gave me some feedback comparing the two cars. I wanted to share this as a track enthusiast and since he attends the track so often he has experience driving the Chin Miata's, NSX's, BRZ and Cayman R as a comparison.


"Hey Jeremy,

Long time no see!

Yes, that is me. I was able to drive both the GT350R and the GT350 Track Pack. Hands down, the GT350R is the best track car I have ever driven, and that includes our track prepared Chin cars. HANDLES better than our Cayman R. The turn in is extremely sharp, and you can toss the thing into the corners like a Miata or BRZ. I was absolutely stunned with the performance of the car.

On the R, a lot of the sharpness has to do with the magnetic shocks and the carbon fiber wheels. The wheels are 19x11" up front and 19x11.5" out back, and only weigh 17 lbs! You can also feel the difference on corner exit, as it feels like it revs a bit quicker than the standard GT350.

Bang for your buck, as a dual purpose street/track car, the GT350 Track Pack is the better buy. It still comes with a lot of the neat toys that are on the GT350R (same magnetic shocks, same drivetrain, same body panels except for big rear wing and front splitter on the R) but different wheels and tires, which makes a big difference on the car. The R is on Pilot Sport Cup 2's while the standard GT350 is on Super Sports. I feel that if equal tires were on both, you wouldn't notice too much of a difference. The magnetic shocks are absolutely mind blowing on a track like Sebring.

There are some other neat toys on the car, such as valved exhaust to keep it quiet if leaving the neighborhood early AM on the way to the track, as well as shift lights integrated into a HUD that act similar to a MoTec shift light system (lights come from each side, meet in the middle and flash at peak RPM), and best of all - Ford warranty's track use for this car.

As for weight it hides it's weight extremely well, honestly can't tell that it weighs 3,600lbs. The brakes were actually more impressive than I thought. It's a trackable pad from the factory - we were running short course on stock pads and fluid, which is notoriously hard on brakes. They had incredible bite after the 3 laps, and could brake as late as I do in my BRZ for Turn 7. Apparently Ford is also putting a DOT 4 fluid in from the factory. No sign of fade whatsoever. Both the R and base GT350 are running a 2 piece rotor and 6 piston Brembo caliper. The coolest part is the replacement cost of the 6 piston caliper - $299! Consumable parts seem to be stupid cheap for this car.

Lastly, the Recaros they have put in the car are a big step up from previous Recaro factory seats - had no problem staying planted at all."

And a video of his driving.

While I don't own a GT350 I thought this review was worthy of sharing. Hope you guys don't mind. The GT350 is a badass ride. :thumbsup:

Awesome spot on description and feedback Jeremy!

I also have run with Chin Motorsports (2x so far) at Sebring and on my last event was able to get signed off for Solo. The GT350 is absolutely a great car and very fun to toss on that track. Although I have about 20 track days (7 so far at Sebring) under my belt, I have only been HPDE'ing since early 2015 and I have more fun on my GT350 than I did with my much faster Z06 especially at Sebring. The new Shelby even as good as it is really hones and improves your raw skills more than the C7 does IMO. Like you said, the GT350 is a bad mofo ride!

Maybe I'll see you guys on the 18th! :thumbsup:

Jeremy, thanks for the nice video of the R model going through it's paces.

Just a couple of questions and comments.

Did you have a base R model that comes without a radio, A/C, navigation, rear camera and other items such as the sound deadener and no carpeting in the trunk or an R model with the Electronics Package? This will not equate to a lot of weight reduction but it will certainly make some difference over a long race.

In addition to the wider wheels and stickier tires the R model of course deletes the back seat along with the resonators on the car and also it must be mentioned that the spring rate on the R model is ~25% stiffer on the R model versus the Track Pack car and I also believe the car sits a little lower for a better center of gravity based on slightly shorter springs and a lower tire aspect ratio.

When I drove both the R model and the Track Pack cars at Sebring there was no comparison between the two cars especially given a race of any length and hopefully you would agree with my assessment?

:cheers:

I wish I could tell you but I didn't actually drive the 350's. I just posted a conversation I had with Scott about his experiences. I have no doubt that I would find the GT350R the quicker car for sure. With lighter wheels, downforce, and stickier tires I don't see how you couldn't know.

The R shows its advantage & capabilities with equal or even semi-equally skilled drivers. I'll give you a real life example- at Sebring over the weekend one of the guys I know has an R, bone stock. He has more track experience than me but I am not too far behind in terms of abilities at Sebring. We were about 3-4 seconds apart per lap times.... we even analyzed & talked about it afterwards.

A key common denominator is the major difference in tire grip and his more unsprung wheel weight. He's able to corner better (meaning faster) and exit out quicker (meaning greater corner entry leads to higher momentum out of turns). Those Cup 2's are a big factor. He even mentioned it just sticks thru turns and goes... he's so used to rotating the car via power oversteer but the R prevents that due to high grip. Add in the less weight of the R plus some suspension stiffening, the R's advantage also slightly increases.

Is it night & day meaning pole to pole? No. But there is a difference stock vs. stock. Adding Cup 2 tires on a non-R will lessen the gap but the R should still come out ahead by a tick or two. If he drove mine, we estimated he'd probably clock lap times two seconds slower than on his R.
