I just picked up my 2001 lexus is300. So far i have an injen intake, tanabe hyper medallion exhaust, and some tanabe nf210 springs and tokico shocks on the way. My first question is : Do you guys think that i will need a camber kit? Im thinking just an alignment but i dont know these cars well.
Second question is, i wanted to purchase headers and a downpipe, will this trigger my check engine light, does it remove any O2 sensors?

 

Do you want the camber get to bring your car back to factory spec or do you want it to go hellaflush. In either case you may want to invest in it, though the IS300 comes factory with negative camber.

Which headers and B-pipe were you thinking?

 

i want pretty close to factory spec but doesnt have to be exact OEM. Im not going hellaflush, been there done that, and i didnt like it overall. Too much headache. That is why i got the NF210 springs which is only approximately 1.5 in drop.
Headers i was thinking about Megan or Topspeed, i was going to investigate which is better for exact fit and minimal alteration. B pipe i have no idea. I was thinking Megan racing too since it is only a little over $100. I'm also planning on doing cam gears and a tune and debating with SAFC2 or the Greddy standalone.

 

I got rear cambers when I was lowered on springs, didn't need them up front

 

What springs did you have? Same drop as mine?

 

I have the Tanabe GF210 and hey drop lower then yours. I just took my car to get a alignment and they got it close back to factory. I never had a issue with Neg camber wear on my tires and i had my springs on for about 2 1/2 years now, Hope that helps

 

This helps alot, thanks! I will just do an alignment afterwards.

 

This.... same thing with me. You'll be good with just lowering it!
