Having read a couple of previous threads about KYB front shocks (or lack of) for the 20VT's, there's mention of the Alfa 155 Q4 model fitting the 20VT; can anyone confirm if this is correct and is it a direct fit?

I'm also led to believe that God (otherwise known as Barbz!) also managed to fit a KYB variant to the front of a 20VT; if someone knows which model these were off could they please PM me the details?

Also is there any difference between the 20VT and the 16 VT fitting?

If I recall the thread it was the Q4 shocks that were used. Also, again iirc,they fit but lower the front by 10mm or so.

16vt shocks are interchangeable with 20vt. Bilstein sell B6 to fit both.

Shocks to fit a wide body Q4 should be the same. Some 155s were narrow body with the narrow track, like a Tipo. I'm not sure if the Q4 ever came out narrow track but if it did these shocks are different. I used KYB shocks and springs from a narrow track 155 in my Tipo turbo conversion.
