I've a series 1 Berlina wagon. I installed injected LPG setup about 20k ago. I know FE2 is loved but I don't like the sports suspension firmness/lowered height. LPG installer said no need to change FE2 rear springs to Holden LPG springs etc. as FE2 is more firmer & it would be ok. What's the cost of doing complete changeover to standard suspension? Car's very well looked after & runs great. It has 220k on the clock. Please recommend a suitable setup considering it's a LPG cylinder in spare wheel well. I like softer ride i.e. statesman like. I know Holden had a special LPG upgrade suspension kit for duel fuel cars. Also, being a 2003 VY build, did Holden got rid of the rear suspension inner tyre wear issue?
