Will any of the parts here make a difference in the performance of my Speed 3?
Or does it already have them all or better ones?

 

those are for the regular 3. the mazdaspeed accessories haven't been released yet although from certain press outlets it looks like they'll have CAI, catback exhaust, coilover suspension,sport springs, lightweight 18" wheels available. info should be available in another month or so...

 

btw, you seem eager to upgrade, how's the learning the clutch thing going?
and to answer your question in another post, if there was one upgrade, i'd get the coilovers... car is fast enough for me, i'd like to be able to corner better =)

also, given more time, there will be plenty of aftermarket parts, not just mazdaspeed stuff.

there's a review from the laguna seca test including the mazdaspeed accessorized speed3

 

Don't rush into coilovers if you plan on keeping this your daily driver. Although they give you the ability to tune your suspension more, they will absolutely destroy your stock struts before you know it. A lot of times a good set of progressive springs does the job just as well, but are much more compatible with other stock suspension parts. Just my $.02 ...

 

not really eager to upgrade. Just testing the water. I'd lik to know what my options are for the future. Since my Dad insisted on getting the extended warranty i'm guessing i'll need to stick with the mazda speed upgrades since they'll be approved by mazda and won't void it.
