Need help deciding what to mod next
 

I find myself at a point where I don't know what to mod next.

For starters my car is not my daily driver. Originally I bought my car as a weekend cruiser, then I met the local GT86 club and that plan sailed away. (anyone else had that happen?:bonk:). So my car is currently my weekend cruiser and autox/track car. I think in the 18 months I've had the car I've only done 2 trackdays and 5-6 autox. I wish to keep going to more autox events since they are helping me improve my skills, but I haven't done more since I don't have much spare time.

What I wish to get from you guys is pros and cons for some of the options I've thought out to buy next. Some have sparked big debates (pulleys), some don't have much threads on them (swaybars and endlinks). Perhaps you would advise I upgrade something else I didn't think of

My current list of mods:

Brakes:
Endless Steel lines
Endless e-slit slotted rotors (front and back)
Carbotech XP10 pads (front and back)
Endless Brake fluid
Radium Master Cylinder Brace

Suspension:
Tein Coilovers
Tein EDFC

Wheels/Tires
ADvan Neova AD08 225/40R18
18"x8 Sparco Assetto Garas

Engine:
HKS Drop-in
Ecutek Stage 1

Exhaust:
Invidia N1

Body:
Speedfactory v1 rear diffuser
cheap ebay Side skirts
cheap ebay spoiler

Audio:
A whole bunch of stuff to list, but basically amp, headunit and compact subwoofer.

Right now I've pretty much decided on 3 options:

Option 1:
Perrin Sway Bars (Front and Rear). Deciding on perrin since they are not as hard as other brands, and I can dial in more hardness if I want to
Perrin Endlinks (front and rear) since they are recommended upong changing the sway bars. and they are stronger than OEM.

Option 2:
Catted Frontpipe (I'd hate to go through inspection next year and find out my car doesn't pass emissions)
Overpipe
Intake hose

Option 3:
CAI Intake or Perrin Big MAF intake
Intake Hose
all Pulleys

Option 4:
What do you guys suggest? Did I overlook some other part I should mod first?

Based only on reading posts (mine has not hit the track yet) you may want to look at upgrading axles. The stock ones are good enough for unmodded but once you start getting up into the level you are at they can break.
Just my 2 cents worth based on WAY to much time spent on here.

Forced Induction

Forced induction would be great but I got a $900 budget.

Option 1 then!

i personally vote for upgraded swaybars. especially since you auto-x.

Headers

wait until you hate something. change that.

you're welcome

My invidia n1 has been on my nerves since I got it, because it starts car alarms whenever I get home. Otherwise I love it. The Q300 is an option... but I was thinking as something to do at a later date.

Have you ever thought about a strut tower brace? I bought the GrimmSpeed one and while I don't have any empirical data, there was an immediately noticeable improvement in the way that the chassis felt.

This is easy, I'm guessing that you're still NA so if you want 20 more WHP and 15 more WTQ and have access to e85 (ethanol) in Peru, then get the Moto-East flex fuel kit and e85 tune for your ECUTek setup. $650 + cost of the tune (don't know how much that will be).

PrimeMotoring and JamesM also do but I don't have links to their kits. I would stay FAR away from FA20club and Visconti's offerings due to so much bad word of mouth and an exploded car running their stuff.

Alternatively you can dump the ECUTek setup and get an OFT and run straight e85 with Shiv's off-the-shelf (OTS) tune. You can swap back to regular gasoline anytime with a flash. $550.

Sorry no ethanol around here.

:(:(:(:(:(:(:(:(:(:(

If that's the case, and you're going to be tracking the car, then I'd highly reccomend an oil cooler. In your price range, specifically the Jackson Racing Oil cooler kit

Did you do both front and back?
