Would I need a camber kit for Road Magnet Springs on Is250?

With 2 inches drop, I would recommend camber kit to save your tires.
Road Magnet springs work for both AWD and RWD.
Also, they are linear springs which makes it a lot more predictable in handling.
It has stiff rates comparing to other springs so you better pair them with shocks like F Sport, or Koni. This spring will kill the stock shocks pretty quickly or at least you will bottom out with stock shocks.

1. AWD/RWD springs are interchangeable
2. Camber does not kill tires as bad as improper Toe alignment
3. No you don't need a camber kit, it depends on what you want. 2" drop is a lot for springs, but not that much for a drop in general.
4. RM are not stiff at all, H&R/S.Tech/EibachPro are stiffer
I'm running them with -1 camber up front and -2 camber in the rear (all natural, no camber kit).
My toe is 0 up front and 0.10 in the rears

Road Magnet is STIFFER than F Sport which is made by Eibach.
According to Road Magnet website https://www.roadmagnet.com/products-...s/lexus-is-250 , "Road Magnet Lexus IS250 Lowering Springs for the AWD and RWD drop the vehicle height 2" all around with a front rate of 625 lb/in and a rear rate of 550 lb/in " This translate to 11.16 Kg/mm front and 9.82 kg/mm rear which is as stiff as some coilovers. Road Magnet spring rate is far stiffer than most of other ones, at least it is almost twice stiffer than OEM spring rate.
Other springs rates:
OE Rate
4.5kg/mm front
5.2kg/mm rear
Swift Springs
4.6kg/mm front
5.2kg/mm rear
Tanabe NF
4.9kg/mm front
5.8kg/mm rear
RS-R Downs
4.48kg/mm front
6.0kg/mm rear
Tein H-Tech
6.0kg/mm front
6.3kg/mm rear
F Sport spring rate
F-Sport by Eibach
4.7kg/mm initial rate front
4.0kg/mm initial rate rear
6.6kg/mm final rate front
7.0kg/mm final rate rear

RM rate:

Yeah right, "NOT" stiff at all??
Can you read? Can you do simple math too?
H&R, Eibach Pro are stiffer than RM?? Please back up your wrong claim!

You still can't back up your wrong claim 
Road Magnet Spring has STIFF rate and is stiffer than most of other springs including H&R and Eibach. Don't be too stubborn and not accept the truth.
And yes I have driven on them and even tested them on autocross. Have you?
If you post more, please back up your claim and stop saying non-sense stuffs without thinking and better yet, just keep it quiet.
I guess this is the end of discussion. I'm not wasting more time on this thread.

^^ O.K. guys.....let's knock off the bickering. I'll let the op who posted his original question decide what he wants to do. Technically he doesn't NEED a camber kit. If he wants to return the car to closer to factory specs then he does. We can even go on to say he should get toe arms also since toe ruins tires even more than camber.

Lmfao funny guy you've driven on F-Sport and Eibach, but you have not driven on H&R, RM or S. Techs so you shouldn't talk about them. I did not talk about F-Sport, Swift, H. Tech, because I've never driven on them. You should learn more about the nature of linear springs and how they feel against progressive springs too, i dont just mean knowing what they are, but how they actually differ in feel. Yes I auto-x, glad you asked. And sorry to see you getting so mad writing me essays and googling technical specs, next time keep em short cuz you know, tldr. kthxbai. /thread

Not only did you make wrong statements but also make wrong assumptions. Also, all your blah blah blah adds nothing to back up your claim.
All i was saying is:
1. Road Magnet has stiff spring rate and it is almost twice as stiff as the stock spring rate.
2. Road Magnet spring rate is stiffer than many other springs rates.
Either you are too shallow to digest these facts or are stubborn enough to keep arguing on the wrong side.

Hey Is250916
Excuse the drama going on here but I find this very helpful. https://www.clublexus.com/forums/bui...-swaybars.html
Like Sffd103 mentioned if you want to get specs back to stock then yes, if you want a more aggressive stance going more performance minded then just get the camber settings to what reyoasian has. -1Front & -2Rear
It is really up to you and what you are looking for. In general the rule of thumb for lowering is anything more than 1"-1.3" you should get the kits but it also depends on the car, where like on ours we have the ability to adjust enough of the settings to be reasonable on the tires.
