I've been trying to figure out if these two are interchangeable. I see vendors listing fitments for coilovers that say they will accommodate both. Is this true? Reason I'm asking is because I have the opportunity to buy some coilovers for the GS350 at a ridiculous low price and I was told they will fit. I just need to be sure. TIA!

Pretty sure when I looked it up for someone else in another thread the model numbers were the same.

Okay. That makes sense. What makes me doubt myself is when some companies list the IS and GS under different numbers, but I'm sure they're the same thing and they want to charge more for the GS imho.
