Hi Guys, Ive redone my front suspension setup but having a whole load of problems with it.

So Ive taken off the OEM mounts and put on the Baker BM top mounts. ive also fited the adjustable drop links.

I set the ride height to be the same as it was before but it was a lot lower. I raised it once and Ive raised it twice because it kept bottoming out all the time. Its not bottoming out all the time now but on big bumps its bottoming out really hard. So hard that this evening it activated the knock switch on the fuel pump!

Ive raised the car to higher than it was before but its still doing it! What can I do?
The damping is on max which doesnt exactly solve anything.

**SOLUTIONS**

- Im running 250lb springs, could go to 300lb but i like the current spring rate.

- I could raise the car more but the front will be a lot higher than the rear...

- I could get the shaft of the shock turned down in a lathe... however this would mean having them off the car and sending them away which I dont have time for!

Thoughts and advice please D:

raise the rear too, its too low anyway.

I doubt you would want 300lb springs, im running 315 lb kw springs on my ast's with iron block and 23mm bars.

Does sound like they are a bit soft...but Im running 250 springs with a much heavier lump than yours...so thats very odd.
Defo sure they are 250? Maybe try 275?!

(although I would second Welshy with raising the rear abit, amazing how it helped my car imo)

I take that back, I'm on 275s!

havent got the time to raise the rear. im concerned now that ive set my droplinks up wrong and they are pulling the car down. will investigate tonight.

Droplinks wont pull the car down fella! All you are adjusting is the heigh of the arb in relation to the car

its very annoying... spent vast amount of money on this and now I have to run higher than before and bottom out over big bumps :/

It may help if your shocks were on the correct sides and them drop links were set up correctly mate

yep... blahhh another afternoons work D:

250 wont be soft with an alloy block, ive been running 185 with the iron block for a few years!

standard is around 120.

are you sure its bottoming out not just going coilbound or the damper making the bang?

I had a bilstein with a damaged lip seal so the lower leg had water in it, which wiuld make a bang on big bumps.

water doesmt compress like air! they were inverted type though, which afaik you have avo's so they will be std.

well know for leaking and not working great

I like the 250lb springs so I dont think spending any money on those is actually going to help at all.

Its bottoming out afaik. The adjustable ring is very far up the housing and the shaft is about 30mm lower than it was before.

Only way I can think of fixing this is to get the shoulder of the shaft turned down so that the entire shaft is moved about 30mm higher. It will give me loads more travel.

Sounds like you're going coilbound, raising the car up on the adjustable platform will make it even worse. What length springs are they? You probably want around 10" springs at 250lb, although that's dependant on damper length.

As allan says, what length are your springs?

Turning down the shaft on a lathe is a waste of time.
