It seems that some of the lowering springs or coil overs is different between IS250 & 350, F-sport & Non F-sport.
For example, the RSR Down springs I installed for my IS250 Non F-sport seems like the Half Down for the F-sport which is ****ty for me coz my car can't look like Stich's or Bruteshot's.
When it comes to aftermarket suspension parts, is there any difference between IS250 & 350, F-Sport & Non F-Sport ??
Below is a pic of my car :

Looks like Half Down, are the drop specs the same for non f sport? 30-35mm etc?

The other guys probably have better comparison pics but here's mine

See the different specs :

RSR Japan IS250
RSR Japan IS300
RSR Japan IS350
RSR USA IS250/350

So confusing

ISDAS

RSR made this super confusing, I think even they are confused .. (swapping red/blue label stickers as discussed before ) and listing downs as super downs etc etc.

So.. by the above

RSR Down Drop (JP)

IS250 - specs sound right for the pic you posted?
F - 25-20
R - 15-10

IS300H
seems they have an option for an unkown reason to get alternate down's that arent half down's.
F - 30-25
R - 30-25

IS350 as per 300H
F - 35-30
R - 30 - 25

so either RSR USA using incorrect specs (doubt it considering some guys have 250 with rsr down and it looks a lot lower than your pic eg below) for the 250 based on the 350 specs , or they re designed the spring for the US market??

eg IS250 with RSR Down which looks similar to my drop posted above.

Thanks so much for your input .... I'm more confused now ... lol
Seriously, it could be difference between F-sport and Non F-sport instead of IS 250 & 350....
Or left hand drive vs right hand drive...
How I wish I can have your kind of drop !

ISDAS

I know it would be a pain in .sg because of $$, but maybe try Tein S Tech?

Mr_VFS1

What is the model number from the springs you ordered? Maybe you can match it up to see if they made a mistake in the ones they sent you because someone else on the forum ordered down springs and they got superdowns instead.

felixlau

Tein S Tech drops lower than F25mm/R15mm ?
Tein is available here

I can't find any info on the box except the pic below... but it should be correct.
For IS250, based on the specs, drop is lesser than IS300 & 350...
I'm just curious (in U.S.) if you guys get a lower drop for your IS250 Non F-Sport with the RSR springs...

Mr_VFS1

IS350 and IS250 and even the IS300H All have the same drop on F-Sport or Non F-Sport. The only difference in drop is on AWD or RWD which should be stated when you order it under specifications or something like that. I ordered the down springs for my IS250 F-Sport which are the same for the Non F-Sport models also. There's no difference.

Mr_VFS1

Also, I am assuming your wheels are 20" and Stitch is running 19" wheels so his will look different then yours do. Bruteshot and myself are both running 20" wheels so with down springs should look the same. I haven't gotten mine yet but I will post a pic as soon as I do.

FINALLY! Someone lowers it to the appropriate height. Great fitment, how much did you drop it?

Boomin

Camber issues, maybe too soon to tell but inner wear?

Looks the best

ISDAS

bit lower than 1" but I did not get proper measurements before installing, either way very happy with the results.

camber etc was no worse then when I brought it in - infact better , again failed to get a copy of the prinout lol sorry.

someone else has posted it up before but either way assuming you get the right model number cant go wrong with RSR it seems!

ISDAS - a bit off topic but are you running any spacers?
