My first mods

[Super Ace-K]

Well after recieving my very first S12 from Northerner i'm excited to get stuck into some modifications. My car knowledge isn't that great to be honest but that'll change soon hopefully as i'm trying to get into mechanics but for the mean time I'd love to know any advice or help people could give me.

Things i'd love to get done at the minute would be;

Steering wheel/boss adapters etc
Seat
Suspension/Coilovers

The coilovers being the big one as I've been reading there are no real straight swaps for the S12 and it takes a good bit of work to get them sorted.

What about these? I'm always skeptical of things such as these that say they're S12 fitment.

Cheers, Chris

(Also, my main goal is to get the silvia converted from Auto to Manual, I know it's been covered lots but if anyone could help me out there would really appreciate it aswell)
