Franco Smith's men have played some fast, attractive rugby in their five match winning run but will be coming up against a Stormers' blitz defence that can stifle out a team's creativity.
Ali Price has been named on the Glasgow bench but knows what to expect should he get the chance to come on against the URC champions.
"If you start taking steps around the breakdown, you'll probably have to go yourself, because if you take steps and try to distribute then you'll end up in trouble with their line-speed," said Price in The Scotsman.
"As a nine, when you're playing against a team who really fly from out wide in defence and are pretty erratic, it's a different sort of challenge. You might get more opportunities down the side. So a change of direction will be important. There are strengths and weaknesses to every defence.
"We've found a bit of form recently and a way to win games, which is encouraging. Winning becomes a habit, and over the past year-and-a-half or two years, we haven't quite strung together as many wins as we'd want to.
"We're far from being the finished article. We've still got a lot to improve on and we know the Stormers are going to be a massive challenge for us. But we're happy with how things are going at the moment and the way that we seem to be trending."
International duty and the good form of George Horne has limited Price's starts in a Glasgow jersey this season but the British & Irish Lion accepts competition for places is healthy for the team.
"For any player, it's obviously frustrating if you're not playing, but I do understand the process as well," reflected Price, when asked about his drop down the pecking order. "Other guys are playing well. I respect that. It's great for the team environment and the squad if other guys are performing and taking their chances.
"So, I know my place and how I fit into the puzzle, and as long as the team's going well and I can help, then that's all that really matters."
