Been given a set of king spring for my car-just not sure if they will do the job

[VTLS1]

Hello,to all. Have just been given a set of king springs for one of my cars but all the info i can find tells to many different stories. So anyone have these in their car & is your car V6 or V8??
King springs Front- KHPR-19 these appear to be super lows
King springs Rear- KHRL-46 SLHD these appear to be ultra lows or super lows heavy duty.

From what i can find so far the rear springs will be okay in either a V6 or V8 commodore. But for the front i have been told they are V6 by some people & V8 by others,then a few say either V6 or V8 will be fine. I dont wanta stuff around putting them on my V8 when i should be putting them on my V6. So any help etc is appreciated.

The rears you have are for VP-VS superlows
Not sure about the front though...
Catalogue
Edit: Just read the catalogue better and seen the rears you have are also ultra lows for the VT's sorry. But yeah I cant see the part number you have for the front anywhere in the catalogue

i managed to figure out the rears are all good on a v6 or v8 vt. its just the front i am worried about more than anything. dont wanta put it in a v8 & the fronts sitting on the ground or put them in a v6 & the fronts up in the air like an old school dragster,lol
