okla bro like that if you like it...but h&r is stiff a bit la bro, one jeembo won't slam down the car but if 2 jeembo's are in then it'll drop to 1 inch...just to explain how hard it is la...if i were to use the h&r race ones then my S will be numb like "batu" oredi and yes i am so going to get it one day:)
