This is the best route to go down if you want more power.

Depends what you want though.

For a quick A to B car you could just put an exhaust and re-map what you've already got and sort the suspension with the left over cash.

Whiteline rear ARB and droplinks, anti lift kit, and a good geo setting would make the car more fun to drive, and quicker point-to-point

Definately wrong. You want to read Manifold Relative Corrected.

I have Eibach Pro street coilovers and find the ride like the standard STi suspension, But with less body roll in the corners!!
Had these same coilovers on previous Subaru's and quite like them, Tried other coilovers like Tein, BC's, Cusco's etc and found them too hard for everyday driving!!!

Regarding the brakes, even standard 4 pots can be ok with very good pads and fluid.

I had standard 4 pots on my WRX with Carbotech XP8 pads and Motul fluid. Did the job well.

IMO I think the discs aren't upto much, heat up far too quick to be effective.

Sounds like the wrx can be made good then, just STI boys writing it off by any chance?

Mine were ok, but obviously a full brake upgrade would be better. Depends how hard you drive the car.

All depends what you want and how far you want to go, staying around 300bhp the WRX does the job, anymore you should look at an STI.

Yeah, I'm sticking with the 4 pots but just upgrading to these: http://www.godspeedbrakes.co.uk/~god...id_product=195

Not a lot of money and worthwhile I feel.

The STI route is still the easiest to go down, I've had both and spent a fortune on the WRX just to get it to STI spec, then a bit more making it better.

But if you really want to keep your car there are options available.

Don't worry they ate just testing you to you get to 100 posts then you have passed the initiation test

As above advice from moley
Remap and exhaust
Ring AS performance
Tell him your budget and he will sort you out brake pads and discs and fluid and maybe braided lines and Eibachs springs and bushes /drop links etc
That lot should be well within your budget

Then spend £100 on track day tuition / advanced driving course which would be money well sprent and you have a fast A-B car

Theres always has been, is and always will be arguments for and against WRX/STi.

The bottom line is what you want it for and your end goal.

Big BHP an STi is the better base, 300-320 a WRX is fine IMO.

I'm going to take my WRX to around the 320 mark, staying on the safe side of 350 for the 5 speed trans, add some brakes, suspension and some styling and I've got a great fast road daily driver.

I will however be buying an STi as a weekend toy/track car.

I'm not disputing you're bad driver , it's good to understand your car of what it does and doesn't ... ..

I imported my STi with 320bhp from the factory, how silly do I feel Cost me less than I spent on my WRX and less than what I spent on my classic to get to similar spec

If you aren`t happy with your current WRX`s 270bhp, I`ll say it again, 300 isn`t worth the expense mate

I think the standard subaru 4 pots are utter rubbish - the brakes on my 2002 focus 1.4 are better.

Upgrading brakes is a must mate

Mid 300's is a good safe figure to go for - just makes sure it's done properly and mapped by someone well known in the scooby world

More of a lurker these days ....always waiting in the shadows for another sti to hit the early grave of the breakers section,where they belong just so they can become great donors for the mighty wrx to live a long life :-)

Thanks,Pete
Just fitting a converted £70-90 TD05 16G will take you around 300 at a sensible boost pressure and circa £300 open source map.

Fit some £80-120 pinks, £70-90 Walbro pump and you should be looking at 320.

STI TMIC £150-250, 3rd cat removal and sports cat downpipe £350 should see 350ish.

Make sure the first mod is to sack the cat out of the up-pipe, I think a crow bar can knock the cat out but perhaps it's wiser to just get an STI/tuner up-pipe.

I'm running over 300hp with just 5.1 brake fluid and uprated brake lines. Gonna get some fast road pads eventually to stop quicker, main thing is I got rid of the fade :0

Handling? 25mm prodrive/or similar springs, Whiteline Anti roll bar and droplinks.

All this should be circa 2k and your car will annihilate most STI's you come across, and you'll smile being the underdog.

Going past 2k, removing the aircon and fitting 5kg bucket seats is like adding 15bhp and is easier on the handling and brakes.. I'm not sure if it helps the gearbox, clutch and engine even though I've asked the question for 5 years.

And I did Super One and the Clio cup - I consider myself to be a ok driver too. Any decent driver will max out the breaks way before the power ! Mind you it's been a while since I drove anything with under 550bhp !

Im probably considered to be one of the defenders of the WRX, so this is going to sound a little strange coming from me.

If your WRX is a saloon and your happy with that then PLEASE just go and buy an STI, because it sounds to me like your a modder and to throw another £2k at a WRX that's already mapped to 270bhp is a bit of a waste of money TBH.

Especially since all your talking about putting on it are STI parts, and your driving is probably better than average, you'll be finding the limits of the WRX again very quickly, so your money will be better spent on the STI.

Sell yours and buy an STI and you'll have a much better base for moving forward with your mods.

And no guys i'm not ill, well I hope i'm not anyway, but for some people that come on here asking questions, If like me you Pay attention to what they are saying then sometimes it is better to go for the STI.
