Factory shock and springs

There are no other Lexus cars with separate coils and springs like the late model RC and GS models. One of the reasons I balked at the RC F over the IS F - it was hard to justify buying an 1950's Chevrolet style set up when no other modern performance cars are without concentric springs and shocks. After feeling the GS F wallow in the rear on a hard turn with a bump, I was pretty convinced what Lexus did wasn't all that great.

Not to push any wrong buttons on this site, but it's important to point out that the new M3/M4 has separate coils and springs in rear as well as Audis S and RS lines and at least the Mercedes C63. Again, not trying to start an argument, quite the contrary. Just need info.

But so many things get compromised for the oddest of reasons. The five link on the previous generation of GS is the same as the five link on the 2IS. It seems the new generation of GS is getting spread across the line as well (3IS, 4GS, RC). It's a good way to amortize the design cost, and Lexus/Toyota/Scion (RIP) had a mandate in 2000 to reduce the parts count of every vehicle dramatically. Part of that is using the same configurations across model lines. The other part of it is why small parts are more and more difficult to purchase separately. Neither makes it great for us except at the time of vehicle purchase.

Very well explained. Thank you. I guess it all boils down to cost. We may think $80k gets you the best of everything, but in the eyes of the manufacturer mass production and cost savings take priority. I just wanted to know if I could sell the setup rather than it sitting in my garage. I wonder if the RC would benefit? Would the RCF's setup give them a decent drop and better dampening?

That said, I wouldn't want to run the numbers on the Corvette suspension - it's going to be a lot harder to calculate wheel rates and damping rates (because they are now independent) than it will be if they were coil over shock, but anything can be made to work.
Not just old trucks. Some pretty brand new tractor trailers still use leaf springs and leaf helper springs. Some technologies make a lot of sense to just keep doing it the way it has always been done. Formula One cars had separate springs and shocks at one point in time. Doesn't mean it will win now, but it did then.
