Question for wheel gurus

[baggedestate]

this is my old omega which was lowered on 40mm springs. and had 18x8.5 front with 225/40/18 on and 18x9.5 rear with 235/40/18 on to give you rough idea what these looked like these was et42 with 20mm spacers allround

The red one looks right, sadly the white one is riding high, it is exaggerated by the bigger wheels...

It had heavy duty springs and working self levelling. Ride height was identical with 16" wheels and the 55 profile tyres looked like balloons in comparison. Camera angle also has an effect...

The red one looks lowered, the white one looks at standard height

One month old:
- Bilstein B4 shocks and front springs
- HD rear springs with 5 mm spacer to get rear higher a bit
- 18x8.5" ET30 rims
- Continental ContiSportContact5 235/45-18 tyres

For my usage it is on perfect riding level (with poly bushes installed of course ).

Looks good,  what's the maximum wheel size for standard spring height?

See pic. This is it, if I remember correctly, 66.6 cm wheel total diameter is the max. Otherwise it will touch strut lower plate.

I had 18's fitted to my Omega when I first go it, and TBH it looked bloody terrible with them fitted... was waaay too high, and looked like Id jacked the suspension up....

The rolling radius will be the same, but they will make the car appear to be higher....

Mine was fitted with 215 35 18 tyres, correct 18 inch profile for a Vectra B, so that might have played a part too

Yeah, that'd knacker the rolling radius somewhat
