It’s time to search away on the forum. This topic has loads of ‘discussion’
I went to CRS and had Koni dampers with H&R springs.
My wheels are Leighton LV1 with 245/45/20 front and 275/40/20 rear. Although many fit 275 on the front as standard they are too wide for 8.5j wheels.
I think if you combine 20’s with shorter springs and the original shocks then you risk losing your fillings.
