Title: Lowering my FC Sedan
Post by: Philby on March 15, 2006, 03:43:15 AM
Hi All,

I would like to lower my Black FC Sedan (original front end and rims), but  I don't want to lower it too much, just enough to enhance/toughen-up it's appearance (stance) and upgrade it's cornering performance

I have seen some nicely lowered FCs and FEs but, I don't know what their setup would be.  If anyone has some examples with the specs, I'd be interested in seeing some pics or being pointed to threads with the cars pictured.

I'm quite new to working with springs and shocks so I have some initial questions that may get me up to speed:

1. What will determine the need for new shocks as well as spings?

2. Should I only buy new heavy-duty springs etc. or are 2nd hand ones okay?

3. Are lowering blocks suitable for FCs?

4. Are there any issues with tyre clearance? and if so, what do I need to consider to prevent that being an issue?

5. Are there any tyre wear or camber issues associated to lowering a FC?

I'm sure I'll have more questions as I get going but that's it for now.

Cheers,

Phil

You dont need new shorter shocks - unless theyre worn out. The existing shocker length is OK
New lowered springs are better, cutting second hand ones is not really recommended.
Lowering blocks are fine for the FC
Should be no tyre issues with stock set up
Geometry will be OK after a new alignment.

Theres a guy on ebay who flogs lowering blocks for FC's in 1.5" and 2".  They do the job as I run the 1.5".  I think they were $65 and ali.

We lowered th FCwagon with 3" lower springs front and gas shocks and had th rear leafs reset 3"s and had th spring eyes reversed and had th hangers flipped it sits low and look's FAT. Th EK Kustom has dropped stubs,resert springs and th rear has reversed eyes,flipped hangers and is reset 5.5inches not bad for th daily driver tho th rear can be lifted.

Thanks everyone,

Sorry I havn't responded until now.

I still havn't lowered her yet as general maintenance and mechanical improvements have taken priority.  When I get back to Oz I'll lower her.

NES, I've been watching your build and firstly congrats, it's looking awesome!  I like the stance you have achieved.  What type/size of springs did you use on the front?  I guess 2" blocks for the rear? Any rubbing issues?

Kat58, I'd be keen to see a pic or two of the wagon.  I had a look on the forum but couldn't find one.

Cheers,

Phil

Hi All,

Well it's been a while but now it's all happening.  ;D

I'm going to lower my stock FC Special Sedan, however, I'm not really sure how much to lower it (front and back) to get the stance I'm after.

As I'm sure I'm not the only person who's been in this situation, I thought it might be handy to get a single post with a consolidation of the cars we've lowered, how much they are lowered and what method was used.
Note: This could be useful for others in the future too :).

At the moment I'm considering 1/12 inches all round but I don't really know what stance that will produce as I don't know how much my existing springs have sagged..... :-\

For those of you who've already gone down this track and already lowered your car (any height), would you mind posting a pic of your car and tell us your lowering details?

Once I'm done I'll post a before and after picture.

Cheers,

Phil

Phil,

You realise this is the start of an incurable addiction to modification...

picture the stance you are after, measure the height of the guard at stock level then calculate how many inches lower you would like it.

for instance if you want the guard to sit 4 inches lower than it's current position.

take out your spring cut around 3 inches off your free spring length. (measuring around the coils to make sure you cut the same amount off each side.

re-fit, drive round the driveway/yard to let them seat properly then measure your guard height to see if you got it right.

do this until your desired ride height is achieved.

(you can then take your springs back out and get a new set made to those specs if desired)

Cheers

Ed

Hi Phil

the best way to determine the ride height your after is to park it on flat ground and large enough for you to stand back and have a look afar.

2nd step measure your original height.

3rd step invite 4 large friends and a couple of bags of cement.

4th step arrange inside the car the ratio off cement and friend's to achieve your desired ride hight.

5th step measure the new hight then you can proceed in sourcing lowering blocks and springs.

lowering your car will only look as good as the beholder sees it. Don't forget that it will be lower again if you put the same friend's in it and could cause bottoming out. You will also need a new wheel alignment.
Bob Harris could help with that.

If you want it to handle better lowering only helps a little you should increase the size of your front sway bar and put a back swaybar on if you don't put the back one on it will float in the back when you corner, put Koni adjustables on each corner to stiffen it up more if you wish.

hope I helped

Julius

2'' lower all around is good and won't cause complications it's a safe height and looks  good  ;D ;D my two bobs worth... but if the car sits presently nose up maybe  2" front and 1 1/2'' lower in the rear  may even it up  .....FC427......

Have to agree with FC427 on this one and say 2'', I'd say that would generally be accepted as the norm.

Thanks for all that.

Any chance of someone posting a pic of a sedan lowered 2 inches?

I'd like to customise the height using your method Julius but time and $ are limited at the moment so a simple lowering process is the best option I think.

Cheers,

Phil

Philby, hav a look at NES's build thread,I have bumped it up for you, it has some good photos of his car lowered 2" all round. As he said it does look tough.

Anyway... you deserve a big congrats on your car, great to see it get back to you.
