Wheels or suspension first - GT 1.9
I am trying to decide what to do first to my 1.9 JTD GT. I have had it mapped and now find that it struggles to put down the power, especially at lower speeds and revs. The plan eventually is for suspension, wheels (inc tires), breaks, exhaust and diff (q2 or quaife diff) but it will be done over a bit of time and probably near enough in that order. I also want to look at the ICE and fit that in somewhere but I am able to do the speakers etc as and when.
So, as I am looking to sort the handling and power delivery a bit, what do you think would be best first, lower the car or look at wheels?
Currently I have 16" but think 17" is the better compromise, plus the with is 7,5 on the 17" i am looking at, and I think the 16" are 7 (correct me if I am wrong)
The suspension I am looking at is the Koni suspension kit (with H&K springs).
I am not after super sharp, race car setup so think this will give me a good compromise for a daily driver (one that gets driven through Birmingham and the motorway on the way to work most days). I don't need or want the adjust-ability of coil overs as I know I would not use it. I know people rate the eibach springs but from what I have read, they are quite harsh, so the little bit softer would be better, also why I have decided against 18" alloys.
I have not lowered a car before so not sure how this would help over wheels, any help deciding which one first would be great.
