The Specs: On Paper

The Asetek La Prima and Moza R21 wheel bases are direct-drive, PC-compatible units with standard quick releases. The R21 boasts a higher torque output at 21Nm compared to the La Prima's 12Nm.

The Ugly Truth (Real User Experience)

Users are reporting that the Asetek La Prima is a more functional, less stylish option, but it gets the job done. The wheel feels cool, but some users miss having a round one for older cars and Formula/Proto racing. I've seen complaints about the Invicta pedals feeling off when driving non-open wheeler or proto cars, but a new quick release is soon to be released.

The big problem here is that both products have their own set of issues. The La Prima has some users experiencing notchiness in the wheel when there's no steering wheel attached, which sounds normal but is still annoying. I've seen reports of the Invicta pedals being uncontrollable and only suitable for GT3 racing.

On the other hand, the Moza R21 has its own set of problems. Users are reporting that it can feel notchy when just sitting there turning the wheel, and some have experienced freezing issues mid-game or the base randomly locking on one side. I've seen users having to replace the PCB to fix these issues.

Dealing with these problems is a nightmare. You'll be stuck trying to troubleshoot and fix your wheel base, only to find out that it's a known issue. And when you finally get it fixed, you might still have to deal with notchiness or other quirks. It's like they say: "If it sounds too good to be true, it probably is."

The Verdict

For the budget-conscious sim racer, I'd recommend the Asetek La Prima. While it has its own set of issues, it's a more affordable option that still gets the job done. However, for those who can afford to splurge and want the best possible experience, the Moza R21 is the way to go.

But let's be real here - both products have their flaws. If you're new to sim racing or just starting out, I'd advise you to look elsewhere. Spend your money on a good brake pedal, not a wheel base that might give you headaches down the line.
