were having loads of fun at louth with trucks
we dont allow oil shocks just kit plastic ones we allow free options on inserts ,I dont even glue my tires on
popular tweak is 1/2 million weight oil in front diff thin grease in rear.bearing kits are allowed and upgrade alloy propshaft
popular choice for inserts in complete narrow mini pin touring car tyres
or people just experimenting with 4wd buggy front blue inserts
we also allow additive on tyres
