Sparco Seat Bases utilize the factory seat mounts on your vehicle's floor and provide a flat surface for mounting your Sparco seat. All seat bases are vehicle specific and provide a 100% bolt-in installation.

The 600 Series Sparco seat base is constructed with 3/16" thick steel to provide a strong flex-free mount. In addition to the mouting holes provided for standard bolt-on installation, the Sparco base has a wide metal platform to allow custom mounting of side mounts direct to the base (drilling required). This direct installation is an option for race vehicles where the lowest seat position is desired. The base is powder coated in a black wrinkle finish.

Soft
Fit Type: Regular Fit, Color: Navy/Dark Blue, Size: X-Large
They feel nice, but shrunk a little in the wash. The fit before shrinking was perfect, afterwards it was just slightly too tight. The length before and after was too short for my preference. I do have a slightly longer torso though. If you are normal height then they will likely work great for you. The material is super soft and comfortable.

So soft and attractive
Fit Type: Regular Fit, Color: Heather Grey/Heather Grey, Size: X-Large
Bought these for my husband. He loves the fit and they're so soft and don't wrinkle easily. They're also a nice weight. I've washed them a few times and they don't pill or shrink. Wish they came in a larger variety of colors, but plan on ordering more.

Shockingly great affordable basic T- Shirts
Fit Type: Regular Fit, Color: Black/Black, Size: 6X-Large Big Tall
I love these shirts! The fact they are big and tall is amazing. Better than Hanes, Fruit of the Loom, and Gildan. I am 6 foot 5 and heavier than I'd like to admit. I also have a wide chest 64 inches(Its hereditary). I need width and length! It is tough to find a shirt that is big and tall. Literally it's one or the other. Amazon of all places solved this. I did get two that weren't right they replaced them swiftly. Also for some strange reason white is a tad bit smaller in the same size. Usually it's the other way around with other manufacturers. I could not find black shirts that fit me comfortably for years! I was convinced it would be impossible to ever find any that would fit. This felt like a long shot and it paid off! Which is rare. I do not dry them in the dryer I know they will shrink(Probably wouldn't hurt to wash cold). If you want to dry them and you can I would go size up. Not too thin or too heavy wouldn't consider it an undershirt.

New default shirt
Fit Type: Regular Fit, Color: Navy/Navy, Size: Small
Amazon has again proved that it did good research about what makes a good basic garment. I've been wearing these for a few weeks now and honestly I forgot about them because they just fit and are not annoying and don't look bad. They are good. Also the cotton seems high quality and is soft. Also the small fit as expected.
