    Hello fellas!
    So recently i've been gathering some info about the S203 STI!
    Have heard from a couple of people that it understeers a lot more than the Stock JDM STI!!
    That is due to the tier sidewalls flexing and the stock suspension overloading when pining the front end down!
    I'm tempted on buying a set of RCE T2 coilovers, and Michelin Polit Sport 4S tiers!
    I can't figuer out the alignment settings for this setup, Bone stock S203 with RCE t2's and Pilot Sport 4s.
    The car would be for agressive B road driving and Track!
    Or should i just keep the stock suspension?
    Thanks a lot!
    Cheers!:thumb

    Stock suspension is epic :) Tyres are everything. As an example on my daily vRS Octavia I had Toyo T1R's on when I bought it and it would push forward all the time when hooning about. I put Nankang NS2Rs on all round and it handles like its on rails with very little understeer. The 4 way suspension on the 203 is really good. :)

    I heard that the suspension isn’t that good!

    Doing that, overloads the suspension!

    Of course depends how you like it to feel and what driving you intend doing :) The alignment adjustment is no different to any other impreza same goes for the bits you can add to get more camber, caster etc etc etc :)

    Ok!
    But how would the RCE T2’s stack up to the stock suspension?
    Not in adjustability, but drivability!

    They don't compare tbh. I don't know what the spring rates are but where as with the stock set up I would attack the arbs etc to effect the characteristics of the car more, with the RCE set up I would use the breadth of adjustment to re characterise understeer or over steer. You only really get to find out by doing it yourself on a trackday by adjusting adjusting adjusting. I did this a curborough and it's amazing the difference between spinning and winning by just a few clicks bias front to rear using the click adjustment.

    For what it's worth on track I would run coilovers if that helps :)

    Spring rates are 500/400lbs!
    Yeah.. the only real advantage is the adjustment!
    But id get them for that!
