Hi guys,

Just joined this forum, ive recently bought a 55 blob sti with ppp, cars had one owner from new 40k miles, totally standard car.

My plans are to start doing trackdays again in 2015, on my 03 sti i upgraded to whiteline arbs, drop links etc to stop fuel starvation and improve handling, im just wondering if its worth doing as the car feels pretty stiff with just the ppp suspension?

Any thoughts?

The PPP does not include suspension upgrades. There are however Prodrive springs which the previous owner may have fitted!?

I had coilovers on my 2005 car, which were great for the track but very, very hard on the road.

Prodrive springs for a WRX will be blue coated. I actually believe that they're initially softer than standard springs, although they feel stiffer on the road. They sit a fair bit lower than standard springs.

I popped the following post on Scoobynet a while back as I'm not 100% sure how they're supposed to be: http://www.scoobynet.com/suspension-12/1003018-blu... - No responses (Scoobynet has a lot of useful information on it, but a lot of questions go unanswered unless they're "q: if I change my backbox, will I need a remap? a: Yes! You will blow your car up if you sneeze on the throttle without remapping it to suit a back box!!!! wink )

I've got a completely stock WRX and one with Prodrive springs and whiteline ARBs / links. I'd say that the setup is worth going for on track as it really neutralises the car. The stock car grips like anything but ultimately feels like it's FWD to me, any throttle just makes it scrabble the front and wash out. The whiteline suff means you can get the back to follow around a bit - it's also worth looking at using the prodrive alignment too.

The downside? I'd never do it to my regular road car. It feels like it cuts in to the cars ability to soak up bumpy stuff, ultimately making it a lot less composed on the B roads they're most at home on..... not to mention the lack of comfort (I suspect mine's had the prodrive springs put on without the bump stops being cut down to suit).

I understand the key to avoiding fuel surge is to keep over half a tank. The EJ engine is also known to suffer oil starvation in long high speed corners, most notable tracks for this are Mallory and Snetterton.

And the WRX brakes are far too bloody small!
