GS350 lowering springs on IS350?
So I was wondering whether the RS-R down springs from a GS350 Fsport would fit an IS350 Fsport? Any information would be a great help!

So I spoke with a friend who works a lot in suspension , and apparently the springs do fit, but since a GS350 is much heavier than an IS, they require a larger spring rate. So transferring the GS springs to an IS would make the IS sit higher due to the IS's lack of weight.

Probablyhas the same OD/ID so it can sit in the perch, however, is designed for a much heavier car.
You might see this same issue when people use springs from EX: ISF on an IS250. The ISF springs (because it has the larger engine and "heavier"front end) will make the front end sit higher if installed on an IS250.
