There are many racers on this forum who will be glad to give some advice on your purchase. If you could tell us,
What is your budget? Are you looking to convert to a full rig in the future ? Are you handy with DIY projects?
Here is a list of stands and rigs. Take a few minutes to browse, there are also some video reviews. Have fun.
The Wheel Stand Pro works great for a T300/T3PA-Pros/TH8A setup, many use it.
My only issue is the shifter mount - it is a bit high up IMO. So I made a cheap mount to lower it down. The company now makes a much better shifter mount that is adjustable so look into that. They also made new hardware to mount the T3PA-Pro / T500 pedals in the vertical GT position if you are interested.
Warnings about this stand -
1 - Some people do not like the center bar between the legs. I have no issue with it. I left foot brake, heel-toe, etc.
2 - The rubber feet can mark up a hard floor surface. I put mine on a cheap high impact interlocking foam mat that I had laying around. Cut 1 of the squares in 1/2 and it protects the floor and the stand does not slide on me.
3 - If your in a folding or desk chair that has a high seat, the stand may not be tall enough.
I would recommend you check the playseat challenge, it's between a stand and a full rig, you can fold it and it dosent takes too much space. I got one and I'm really happy with it. It's really comfy and fit most wheel/pedals sets. It's really stable too and fit all kind of person. I'm a big guy and get no problem fitting in it.
