Suspension mods for drag racing

Lets say you,ve got your new engine and box ready to go in what other mods would be needed? Engine mounts , shocks ,gearbox straps etc. Also seen the bars that help stop wheel hop? Need to know for costing up my project.

Thanks

I've got the wheel hop problem too.

Welded chassis horns and rubber lined steel front and rear transmission straps helped a little, but i'll be going for the berg tractio bar and maybe a custom speed parts style transmission support (the one that uses bracing with the shock towers).

Hope this helps,

Depends on how serious your going to get. Minimum is a traction bar on the back, this will stop a lot of axle tramp.
If youre a bit more seious youl need a berg style front mount which takes the front gearbox mount off the nosecone and uses the housing instead, you can still keep it rubber mounted with a setup like this as well.
If your really bent on going fast use a welded in solid mount on the front as well as a solid mount on the bellhousing and tie the frame horns into the roll cage to stop them from flexing. You wont need a traction bar with this setup either.
And get a really good gearbox....

Im using the CSP torque bars, berg intermediate mount, and all OEM mounts. I had some Aluminium bushes machined up that I bolt in to the berg mount (remove the rubber) whenever I am going to beat it up.

This has stopped the wheel hop altogether. Check your springplate bushings, if they are knackered (likely) swap them for urethane, you need to trim the urethane bushes to fit. Its a bit of shagging around but worth it (no squeeks!!!). I use KYB gr2s in the back and adjustable bilsteins up the front... I had bilsteins in the rear, but they were to hard - and didnt help with wheel hop.

As shify said, tying a cage into the frame horns is the sure fire way to go - I dont know what you intend to use the car for, but solid mounting is LOUD - you need earplugs...
