The ironman lift is 40mm not 540mm(?) and with time could go down to 35mm. The CVs sit level with this lift, as they are at an upward angle with the factory suspension.Do you mind sharing where you heard this?
I'd like to get a list of options for body lifts for the 2006+ Grand Vitara, which may be helpful to anybody planning a similar build:
Rocky Road: 2.125" Lift. $249 – Consists of steel over the top style strut spacers, steel rear spacers, camber alignment bolts, and RRO rear shocks. Link
Ironman 4x4: 540mm Lift. $839 – Consists of FRONT & REAR 40mm RAISED HEIGHT Coil Springs and L/T Nitro Gas Front Struts, L/T Nitro Gas Rear Shocks. Link 1 Link 2
Jimnybits: 2"/50mm Lift. £334 – Consists of Pro Comps ES1000 rear shocks, upgraded reasprings, 50mm solid steel billet front strut spacers. Link
Trail Master: 2"/50mm Lift. $??? – Looks like theres several different version of this kit out there, or there used to be. Some seem to come with body spacers and other don't. Link 1 Link 2 Link 3
Dodinson: 40mm-50mm Lift. $??? – Consists of Coil springs, front and rear. New shocks and camber adjustment kit. Link
Let me know if I've got any of this wrong and I'll correct/update.
I've read quite a bit of negative comment on the Dobinson lift, apparently they ride rough and it is noisy.
You also have outdoor auto 4x4 that sells lift and I've read good comments about them, but I have no experience with it.
Lot of people says the RRO strut are too stiff for the weight of the vehicle and the people I know (well in the forums) change the struts for better ones.
