Solid axel vs. IRS

[C4 Cross Fire]

What's your take on solid axel vs. IRS?

[MetaJacko]

Isn't solid better for drag and IRS better for racing (road holding round corners)

C4 Crossfire,

From a cost standpoint, most IRS setups cost a little more, from a dragracing standpoint if the "proper items are used" they are very close unless you are beyond 9.9" wide slicks. IRS axles can easily handle 850 plus HP if the proper design is utilized.

Open road events, if set up right they are so close, too close for a novice driver to get any great advantage out of.

From street driving , the IRS is a bit smoother over the live axle, shocks and springs being the critical issue.

Bear in mind, none of the above are worth a tinker from any standpoint if the design and materials selected are wrong and off design.

The difference in ride quality for me was astounding!

I had a 9", stiff springs, lowered did well on the road race track, rode like a truck on the street.

Now I have the ERA with Jaguar IRS, night and day! The ERA is really smooth.

The difference could be as simple as how they are set up, but I suspect it's because we have some pretty rough roads here and the IRS does a much better job on rough roads (and tracks).

What specific shocks and springs should I get? What do you recommend?
