Has anyone ever tried or probably own D2 Racing coilovers for their Jag?

I have only seen folks do springs for the XF. I doubt many people have or want to put track ready coilovers on a car like this.

But man they are tempting for the price!

There is a reason they are that cheap... and they don't have the greatest reputation.

I prefer to have coilovers instead of springs since coilovers offer more advantages than springs. I tried to find coilovers for Jag but there seems only D2 coilovers that provide aftermarket coilovers for the Jag.

um . i think there is also KW AND Ksport as well

Spires makes some as well

They are no KW or Ohlins, but I have actually heard good things about them. They seem to be durable and do "improve" the handling. Not saying any of this from personal experience though.

KW or any other top shelf companies don't offer suspension kits for this car. Looks like Spires is the only other one:

The spires kit seems like a mix of their spring and Bilstein monotube sport dampers.
