IMO I think it would come down to what you want from your car.
You said you want to just fill the guards a bit.
But is that all you care about?
If you want your car to handle well I would stay well away from pedders.
I wanted my car to keep its stock appearance, so I got some stiffer springs (stock height) and new pedder shocks (as the old ones were stuffed).
But now that I have, strut brace, underbody brace, castor kit, sway bars and polyurethane bushes. The pedders shocks are really letting me down, the handling feels 'nervous' under hard cornering and there is way to much body roll when the shocks go off.
If you want performance, stay away from pedders.
