My mods, i might forget some...
These comments are MY comments, how I experienced them.
RM open air intake with cold air option
For sound its brilliant, especially on high revs. Performance not noticeble, price for mod was IMHO to high. Get lots of compliments on the sound.
Headers
Worst mod i have done so far, Performance not noticeble, Price/performance factor was way to high.
Remus exhaust
Better sound, Much better looks, Can not comment on performance/price, since this was on my car when i bought it.
Advan Model 7 17&18
Better looks, Imported from Japan made the price/fun factor very good.
Track sways
Very stiff ride, just how i like it. Makes car more noisy. I bought them used, very low price. One of my favorite mods.
Yellow koni's
Adjustable for track/road use, Can not comment on performance/price, since this was on my car when i bought it.
Springs
Can not comment on performance/price, since this was on my car when i bought it.
Engine dressup
Is oke to make the lot look a bit better, but really not worth it IMHO, just one of those things you do when you want to mod something. Puts a presonal touch to the car.
Mesh engine cover
Was a DIY project, turned out very OEM looking. Problem with driving in the rain, is that the belt throws all the water up against the rear window.... Still costed quiet a lot for a diy, but was worth it.
Instruments dressup
Stacey's clusterrings with the SoS cf layer makes a nice change, i like it a lot, though fitment was a real pita. Price/looks was oke.
Light flywheel
DaliRacing light flywheel, got it from GerardvanSanten. Very reccomandeble. Got the feeling my 0-60 has actually gone down. Can not comment on price/performance.
Shortgears
When driven around the block/track/twisties, these are a must have, though sometimes on the autobahn i realy mis my old long gears. Coz i did installation myself, i can say that price/performance factor for me was good.
Dali Chip
Gives you a higher rpm limmit, and just those few hundred rpm's make the engine scream like a real racecar. Got the chip used, so i can not comment on price/performance factor.
But most important is the total package, light flywheel, shortgears, higher rpm's, screaming intake... that all toghether makes a big difference over stock, but was it worth it? Difficult question... at the time it was, but these days when economy is striking me i'd say no.....
