Greetings all,

I'm thinking of going with a set of Nitrons. I really only drive my '05 Elise on the track on stock sized R888s. I get about 15 track days in a year. I like the idea of single adjusts from a cost and lack of complexity standpoint.

Here's my question...

Have any of you Nitron Sport owners run the orginal setup and the higher rate Eibachs that come with the Sport Pro setup? I'd like to get some compare / contrast thougths between the different spring rates.

Apologies if this has been discussed before. I tried searching to no avail (Sorry - no matches. Please try some different terms.).

ALso, when upgrading the suspension (mine is a sport pack), is an adjustable front sway bar recommended?

Finally, I was thinking of aligning to the specs in this thread...

And and all thoughts are greatly appreciated.

THANKS!

Frank,

Since nobody else has replied I figured I'd give you my $0.02.

The main thing the higher spring rates solved for me was the "knuckling under" (as Ronin put it) on tight corners. Being an engineer, I wondered if there was a better way to take care of the knuckling under, or at least a different way. So, I got the 7/8" front bar from Fred at Blackwatch. Sure enough, not only much less body roll, but the knuckling under improved dramatically. I went back to 425 lb/in on the front and the knuckling under is still under control. Now I am tempted to try the 1" bar from Eliseparts: Elise Parts -  >  > 1" Adjustable Anti Roll Bar

With the lower rate springs the traction on bumpy surfaces is a bit better, as well as the ride. The bigger bar didn't noticeably affect traction or ride, and if anything decreased understeer, I assume because of reduced front camber. For higher speeds at the track I can see where the stiffer springs might be more appropriate because of aerodynamic effects.

YMMV, etc. etc.

Thanks fpitas! I appreciate your taking the time.

I'm going to have three different sets of springs for the Nitrons, so I'll be able to play with it.

Do you want to sell your BW bar? I was thinking about purchasing one.

Frank,

No thanks, I'm keeping it. I think it's the best change I ever made to the car.* You could ask Fred if he's making more, or else Eliseparts (see link above) has 7/8" and 1" bars available. They're good about answering emails if you have questions.

*OK, the VF2 is a close second ;)
