IRS vs. 4-link, aka: RS vs DSE...

The IRS on the other hand is sprung very soft, yet handles better with less body roll and a way better ride. I'll agree that if you want to do more of a bolt in type rear suspension the DSE QuadraLink is awesome, but if you can spend the money you will not be disappointed in the RS/IRS chassis.

Now you're just showing off I want an IRS in my RS chassis but I just don't have the extra $$

As much as I want them I just don't feel right stealing your vision of wheel themes. You and your builder really own that Intro PT vibe. Even after giving you your due I just have to find my own original style to feel right.

anyone else?

Contact SRIII motorsports. They primarily build custom chassis's for vintage corvettes but do build for other makes. Their cost of a custom chassis with irs will be cheaper than you think.

I will add a little more to the mix, not sure if you have made a decision yet but here's my take.

Everyone keeps talking about how much less the cost of the DSE setup is?? While it does cost less the buy the parts from DSE, you need to remember what it will cost to install the q-link and add that to the cost? Now yes the RS setup will still need to be installed as well, but it will not be as labor intensive as installing the DSE sub frame, frame connectors and q-link. Just something to keep in mind.

Not saying one is better then the other, just pointing out that the DSE setup will get much closer to the cost of the RS setup if your having it done at a shop.

I beg to differ on that. Especially, if it's a custom IRS which it will be more than likely because not too many shops are doing production IRS's that will fit any of their own chassis's except the Roadster Shop. Also, probably any chassis shot can throw together an IRS to make it cheaper, but to actually incorporate R & D into the build, draw it on the computer, watch it travel up and down and move to where it functions properly, then build it is another story. SRIII does make nice chassis too.
