jp low down springs on q45 2002

hey guys as some of you may know i got a set of jp low down springs that i got for my f50 does anyone here have installed any of these springs before on an f50/q45 they are going on my 2002 my mechanic guy is good with most of my work but i am worried he has never done a q45 before is there anyting else he might need i know a spring compressor is needed we got like 4 of this but how about anything else , ? hope if someone has done this on a q45 may help with some information thanks guys.

I don't know about anything special for this car, but tehy are springs. How hard can they be, if he has a spring compressor everything should be good. :shrug:

I would wait for Widebody to chime in before you go forward with anything. And then you can harass him about seeing more pics of his car.

:smiley-rofl:sound like a plan to me!=)[quote=Gao Jian;165467]I would wait for Widebody to chime in before you go forward with anything. And then you can harass him about seeing more pics of his car.[/quote]

springs are simple. cant say i know a lot about the suspension setup with these cars, but it shouldnt be difficult.

You need a spring compressor for the fronts (you said you have that) and the brakes need to be removed up front before you can start.  Takes alittle time but its not hard.  The rear is real easy, no special tools needed.  Good luck  :biggthumpup:

thanks Q i will post some pics as soon as its ready =)

if your mechanic even has a doubt in his mind about installing springs he shouldn't be your mechanic.

no he has a doubt on the car due to all the sensors in it thats all .

The front shocks sit on the LCA.   It's attached to a ball joint.   This is a bitch to take out.  Took me a couple days to figure it out.   Get a ball joint remover tool.   Careful not to rip the rubber boot that's holding all the grease in and keeping the dirt out.   Take some good wacks at it.   Make sure to leave the nut on top so not to mess up the threads while wacking away.   The whole suspension is sitting on the joint and the LCA wants to move upwards.   You are going to have to fight it all.   Like WideQ said the rear is a cinch.   I didn't even use a spring compressor for the rear.   You'll just have to apply load on the LCA to compress it while taking out the bolt which can be done using a jack.

Also the fronts all you really have to do is take the calipers off but not completely.   Just unbolt the lines from the shock and let it sit off to the side....the rotors can stay on but it ways a ton all together.   I'd say about 40-50lbs.   Imagine trying to hold that with one arm while trying to put the nuts on the top with the other.If you want to take the rotor off then that is another bitch.   You have to take the rotor cap off and then there is big ass nut.   I think it was like a 32 or 34mm.    It's dented so you'll have to straighten it and then back out the nut.    The bearing should slide off with the rotor or just the rotor might come off.   Mine one of the bearings kind of came out in seperate pieces.  

If this is an experienced mechanic then this is nothing new..

PS.  While I took the ABS sensor out I cleaned out the junk on it.   Dirty grease and probably some bits of metal.   The sensor is magnetic.

How much did the JP springs lower your F50?  thanks

still have to measure exact inches ill let you know this weekend when its put to the ground we had it on the lift due to the mounting of rims and tires .

I appreciate that.  I was hunting for F50 springs the other night.  Lots of options but most of them are only 35-40mm drop.

any specs on springs???

still havent drop the car on the ground they had to transfer my air pressure sensors from the stock rims to my 20 inch rims specs are on the box but i cant read japanese hahahah.

moving the sensor is a hassle...just drive without it...The warning comes on about 30min after driving awhile.   My around town driving it never comes on.

why is it so hard? i was going to try taking theme off monday morning because of the rain all this weekend , what light does it come on on the cluster or the navi unit? i can drive with a light on only if there is no type of beep or something :smiley-rofl:

if you have a pic of the box maybe someone can translate.  there is a gentlemen on clublexus that will translate in the VIP forum.

I just finished changing all 5 wheel studs on the drivers front.  Someone overtorqued them and damaged the studs.

pics of the box would be great i can get it translated.

navi unit and the little light on the dash that looks like a profile of a tire on the groung with an exclamation comes on.    Navi you just click ok or whatever to get rid of it.
