I lowered my 97 Lude for autocross several years ago with the Eibach Pro Kit springs (1.4 drop) and liked them very much. Combined with a bigger rear anti-sway bar, it was a very nice mod. Now I am thinking about lowering my 99, but am seeing the Tein S-Tech springs (same drop) at about half the price of Eibach. Tein wasn't available in 98, so are these two similar in quality/performance?

Also, it is time for some new spark plugs; what is the best thing to put in the Lude? I have bolt-ons only (intake/header/exhaust) and burn 93 octane. I'm not interested in spending an arm and a leg on plugs, but I can get a set of NGK Iridium IX for about $25. Is this good bang for the buck, or is there something better?

Thanks,

i would go for the Denso Iridiums
there about $15-20 higher than the NGK's
i ran NGK wires and plugs but switched to NGK wires and Denso plugs when i needed to service my Prelude and felt a much greater difference and think i got a little better mileage too
in my opinion the Denso Plugs are better bang for the buck than the NGK's

 

I guess you would say iridium is the way to go then.

Denso certainly justifies the significant extra cost by claiming their iridium plug is better, but I have seen tests that indicate there is no difference (at least in racing applications, which mine is not). Anyway, I already snatched up the NGK IX deal off eBay; it has to be a great improvement over what I have now.
