Can anyone confirm sport springs? Are they base springs, nismo spring stiffness, or something in between??

So at minimum you guys are saying with a sport package euro shocks get a front sway bar? What's our size and how thick does whiteline get up to?

Unless something changed for 2013, sport and base springs are the same.

Correct. Springs are the same. 2013s get a damper tweak over the 09-12s but other than that they are the same.

If you do a quick search there's a lot of information on the various bars offered for our cars. Whiteline is always a good choice but there are many others.

You might as well order the whole front/rear set instead of one bar (unless you are in some AutoX class that only allows a front bar change.) Good idea to read up on how the bars work and affect handling so you can make an educated decision on what to go with, and understand how to set them up. There may be a lot of trial and error associated with getting an adjustable bar setup "just right" for you.

Remember, what works for one person might not always work for another.

I've been through it a million times before. Trial and error costs money which I'm not into throwing away. If what works for someone gets me close enough, that's fine with me.

Well pretty much any bar choice will be an improvement over stock. Stillen and Whiteline are popular. Eibach too.

By trial and error I meant testing the numerous adjustments on the bars. Most of them are multi-adjustable front and rear.

I think he meant trial and error in regards to the settings on the adjustable bars, not trial and error meaning buy several different bars and see what works best.

Read my mind. ;)

Gotcha.

For what it's worth. I went with Stillen front and rear, and used the middle stiffness setting for the front and softest setting for the rear. Keep in mind even the softest setting for the aftermarket bars (at least Stillen) are far more stiff than the stock ones. Oh an the rest of my suspension is stock.

Back to the seats, does getting aftermarket seats without airbags affect insurance?

I've always wondered about that. On a street car I'd be reluctant to give up my side airbag protection. That's why I spent the extra $$ on the factory Recaros when I had my Mustang.

I had a few different sets of aftermarket seats in previous cars. The airbag thing ended up being what got me to switch back to OEM seats with airbags. What concerned me was not necessarily the airbags themselves, but the fact that oem safety equipment is engineered to work as a complete system and I went and removed a chunk of it. It bothered me not knowing what shortcuts were taken in other parts of the srs system since there were side impact airbags in the seats.

Hey Op I noticed you're in oc, you want to drive my Z and make sure you like the car before you get rid of the stang?

I don't see why it would, insurance won't cover mods(ie so if you wreck your TT 370z, insurance won't fix broken turbos but they will fix everything else so its stock) but they should still cover any injuries even if the air bad didn't go off.

Honestly though, if you're that worried about it, just transplant the sensor over into the new seat. MCM did a bit on transferring the sensor(its in their how to install seats video)

:iagree:
