Porsche 911 (991) GT3 Cup Steering Wheel 320mm

Porsche 911 GT3 Cup is the most successful race car in the world. Since 1998, 2,395 units of this near-standard vehicle for customer racing have been produced. The Porsche 911 GT3 Cup is the motorsport version of the 911 GT3 and is based on the seventh generation of the sports car icon from Zuffenhausen.

This steering wheel for the Porsche 991.1 and 991.2 GT3 Cup was supplied by Sabelt (P/N 991.347.804.8A), a company with a long-standing relationship with Porsche, and produced in the Sport Line factory. The only difference between the original racing-used Porsche 991.1 and 991.2 GT3 Cup steering wheels is the sticker on the back, which carries the Porsche branding and part number. All other aspects – such as size, weight and quality features like suede, anodising, gluing and engraving on the back – are identical.

Made in Italy.

NICE Shirt that SHRINKS!!
Fit Type: Regular Fit, Color: Blue, Size: X-Large
Loved this shirt right out of the package. Put a little steam pressing on it and it was perfect. Has a thicker softer feel than most casual dress shirts. Ordered XL with the "regular" fit and it could be worn tucked or out without it looking overly blousy. SADLY, after a first wash on cold and tumble dry low, and pulled it out early and it shrunk by almost a full size!!! The sleeves, length of shirt and overall fittage shrunk so that now it fits like a snug large. I've never had a shirt shrink like this, hence, the one star off. I would have given it 2 stars off, but the original quality of the shirt is nice, just beware of the shrinkage factor. Don't put it in the dryer at all, only air dry it. I'm tempted to reorder another but just then never put it in the dryer.

FITS WELL, LENGTH IS GREAT, FEEL IS COMFORTABLE, REASONABLY COOL...MOISTURE WICKING TYPE OF FABRIC
Ok. So I got a job in a retail sort of warehouse and they require collar shirts. So to believe it or not I have struggled to find a shirt that is comfortable, looks decent, fits well, and is not that hot. I bought some Reebok cotton knit shirts and they were too hot, I have to tailor them because they were too long when they arrived and don't fit my body well. I mean the fabric does lay on your body well. I bought some inexpensive polo shirts that are polyester. The polyester is soft finish. So I wound up keeping them to wear. Then I tried some Red Kapp work shirts. The shirts fit well but were too long, and even after tailoring them to length they didn't feel good and didn't feel flexible. So at last I had a polyester university shirt that I like the fit and length and isn't that hot. So I happened to google polyester slim fit polo and came across Amazon Essentials Standard Slim-Fit polo. These shirts are just what I have been looking for. The polyester finish is not really soft or rough but smooth. Kind of like a golf shirt. The length and fit were PERFECT when they arrived. AMAZON HIT THE HOME RUN on these shirts. For reference, I am a whopping 5' 2". My frame is small. Even a lot of "small" shirts fit large. My frame is small but kind of full, if that makes any sense. So all in all I am 100% pleased with these shirts and I am going to put them to use right away. I might even buy some extra one's to wear on a hot day or something. They are just plain polos but have a decent look to them if you wanted to use them for regular wear.

Good budget golf shirt.
I was skeptical to purchase this shirt as it seemed a bit underpriced but I decided to give it a try and was not disappointed. It is very lightweight which is perfect for those warm golf outings. The material does not scratch and is breathable and the quality of the shirt seems great for the low price. I've only worn it a few times but so far I am impressed As for the fit, this fit me very well and I am usually very picky about how shirts fit me. I'd give this a try before buying a more expensive golf shirt, especially for the beginner.

Decent fit, good quality, great value
I'm 6' 4" tall (1.93m), but very thin, so I bought a Small, which is the size I wear for almost all men's short-sleeve shirts (tees, polos, and button-downs). The fit of this shirt is surprisingly roomy, although I'm not complaining given the price point. The shoulders and body could be a just tiny bit more tailored, especially given the easy drape and movement of this pique knit polyester fabric, which hangs where it wants to and glides effortlessly against the skin. I could never, ever feel constrained or constricted in this shirt. I almost wish the fabric were a tiny bit stiffer. The length is slightly generous, but not excessive. The collar lies down properly (no curling at the corners, no unwanted creases), although this is usually the case with synthetic fabric polos. Despite the minor flaws with this shirt, I like the overall appearance, value, and quality, and I plan to buy several more in different colors.

A shockingly good polo shirt!
OK. Amazon Brand. How good can it be? Well, shame on me. I bought one as "cheap" knock around polo shirts for the beach However, what I received was actually a very nice quality polo shirt with a great fit. (Large, "Trim fit" fits me well....average build, 5'9", 155 lbs, 32 waist). While I can appreciate nice clothes, I am only as fashion conscious as the average 58 year old male. With that caveat, I would unquestionably wear this golfing, at summer party or at a causal restaurant . The material has a nice feel, dries quickly and looks like it will resist snagging, though that it a risk with any polyester shirt. I cannot yet speak about long term durability, but I will no doubt recover my $15 investment. I have since ordered 5 shirts more because I lost weight and needed new shirts. Is this shirt as nice at the $90 ones my wife buys me at a "high end", unnamed "preppy" shop? No, not quite. But awfully close!
