Affordable Performance VR CALAIS

[vr.calais]

Have a VR CALAIS with IRS & LSD (i think)
Completely stock, apart from cold air intake..
What can i do for affordable performance upgrades.?????

Are better spark plugs going to do much?
Should i get extractors, before doin the cat back?
does a cat back exhaust give much more power etc?
is a new computer going to cost me the earth?
etc etc :bang:

what ur talking about wont give more noticable power but always good to keep the car running well,

oil change leads pipes plugs belts if u have time just replace stuff so u know the car is solid, then do some searches and see what people have dont for power and go from their

then do some searches and see what people have dont for power and go from their

Thats why i was asking the question..
I have already done a major service.
and looking for more to do to make it more "Solid" / Reliable..

But am looking at doin things to it soon, gotta get some rimz for it, coz the standard ones just dont hold the road as well as i would like.
and then its onto things like maybe exhaust and performance...

a good set of plugs would be a good idea either way....not the 20 bucks each ones though haha just new standard NGK ones would do......i used to think Bosch was good but when i changed me new bosch plugs with new NGK ones the other day (wanted to see if it mad any difference) the revs now sit at 1800 RPM at 100kph and not 2000 RPM as it did with the Bosch plugs. also have better fuel economy (note the bosch plugs were and still are brand new)

as for extractors i have herd they do do allot and some say they do stuff all

As for a cat back exhaust, i have installed one on both my VS and me old VN and it had a noticeable difference on performance and now i can hear the engin roar haha ......its worth it
