Hi. I would like some advice please from anyone. I've just bought a T6.1 Transporter t28 which has been converted to a campervan,but the van is sitting way too low and the front bumper tends to hit some speed bumps. It has 20" alloys but what doesn't help is the low tired wall on tyres too 275/35/20's.The van has Blistein coilovers but garage said they can't be raised any more so I would like to know what best option would be ok please? Was thinking of going to 19" alloys with 255/45/19 tyres, but what would be best lowering springs to put on instead of coilovers so that it's raised a bit but also has a nice looking gap in wheel arch. Thanks all!!
