My experience:
I went halfway with it. Following the dimensions in the TR160 assembly instructions (it's on their site), I ordered regular (i.e. not black) 15-series 80/20 from Tnutz.com (highly recommended, best prices on 80/20 in North America based on my research, you just have to do some imperial to metric conversion) and ordered the DD Wheel mount, Shifter Mount and Pedal Deck from TR (will use my current seat for now). Also ordered
these from Amazon to help move the rig around during cleaning/maintenance.
I ordered everything on the 6th and 7th of August. Other than Tnutz saying 1 part would need backordering, everything was in stock on both sites...key point to remember.
For the 80/20 I just reduced the main base to 4.5" bars (equivalent to 120mm as opposed to TR's 160mm) and the seat supports to 1.5" (40mm equivalent as opposed to TR's 80mm), everything else was to spec.
(Please note: I live outside the US so I have to wait 1-2 weeks extra to receive my orders from Miami by sea)
- The Tnutz 80/20 and parts arrived in Miami on Aug 14.
- Backordered Tnutz part arrived Sept 1.
- The Pedal Deck (which was "In Stock" on Aug 7) arrived Sept 1 to Miami. A few screws were missing, but they sent more parts and a free cup holder and cable management clips a few weeks later, so pedal deck was finally added to rig last week and fits perfectly. The pedal deck is rock solid.
- Wheel Mount and Shifter Mount (also "in stock" on Aug 7) arrived Sept 18 and 21. My shipping company said those two packages didn't have my name on it (compared to the pedal deck shipment), so they've had it in storage for 3 weeks now...should ship this week, so not sure who's at fault between TR and shipping company.
80/20 is 80/20 so I don't mind not having the all black rig (I actually prefer the two-tone look now). Saved about $150 USD doing it this way, but it took nearly 2 months for In-stock parts to be delivered to a US address. It might have been less headaches with SimLab, but a little more expensive with shipping from Europe.
