Posted by Colin Wood on Jan. 16, 2021, 9:34 a.m. https://www.youtube.com/embed/CgvGkA7NRIY

Today, the first-generation Boxster may represent one of the best performance bargains available today, but 25 years ago, it was a groundbreaking entry-level sports car that had a lot riding on its success.

Largely credited with saving Porsche from an economic slump in the 1990s, see how the Boxster went from concept to production from someone who was a part of the process.

Mentioning V8 Roadsters may conjure up images of a massive V8 stuffed into a NA Miata, but the company also produces kits that slot the Chevrolet LFX V6 into a number of popular Mazda products–a kit we decided to use for our budget MX-5 endurance racer.

We recently compared two of the company’s swaps: an automatic Mazda RX-8 and a manual NC-chassis Mazda MX-5? Presented by CRC Industries.

Video: Watch BimmerWorld Make Its Circle Track Debut
Posted by Colin Wood on Jan. 6, 2021, 7:07 a.m. https://www.youtube.com/embed/pKNzTZ_lIXo

The name BimmerWorld may conjure up images of polished, super-fast BMWs for the street and the track, though that hasn't stopped the team responsible for the Bergsteiger from making its first foray into beater circle track racing. Naturally, it’s with BMW, though a few that have seen some much better days.

Sure, the racing may only look like it's a few steps removed from a demolition derby, but beater racing like this may just be one of the most accessible ways to get on track.

Its styling may be polarizing and, unlike many of its competitors, it has front-wheel drive. But that hasn’t stopped the Honda Civic Type R from being a capable track machine.

How does it perform so well on track? We found out for ourselves by looking at the data. Presented by CRC Industries.

Video: See How Toyota Built a Targa-Style Supra for SEMA
Posted by Colin Wood on Dec. 23, 2020, 8:39 a.m. https://www.youtube.com/embed/bZrIbRHzNXQ

SEMA didn’t happen in person this year, but that hasn’t stopped a few brands from creating some unique builds to show off to the world. Case in point: Toyota built a one-off version of its new Supra with a removable, Targa-style roof.

Built as a follow-up to last year’s “Heritage Edition,” the GR Supra “Sport Top” is the latest build from Toyota that is reminiscent of the ever-popular fourth-generation Supra.

Video: Using Race Ramps To Change the Oil on a Lowered Car
Posted by David S. Wallens on Dec. 11, 2020, 10:13 a.m. https://www.youtube.com/embed/En4vfKoV2mw

We have two things going on here:

1. Learn how to perform an oil change on an E46-chassis BMW M3. Figure this is out there for those new owners: What are the steps, and what oil to use. 

2. Watch our first test drive across a set of Race Ramps. Do they make it easier to work on a lowered car? Could this help those without access to a lift? 

The subject is our 2004 BMW M3, and as an added bonus, enjoy nearly 11 minutes of J.G. Presented by CRC Industries.
