I also posted this in the suspension forum which is often much slower.

I had my tokico springs and illumina's installed today. For some reason they didn't put the bumpstops in, none, zero. I provided them with some bump stops off a Koni Yellow set and when I noticed they didn't install them they said they weren't needed. I told them if the car bottoms out it'll destroy something without the bumpstops. They said the aftermarket spring/shock will never bottom out.

Needless to say, I've always read you absolutely need bumpstops, although trimming may be required when going from OEM to aftermarket suspension. The reasons are obvious. Am I missing something here? They said I could come back and they would put them in if I wanted, and I'm thinking I want.

Please proffer your opinion. I think the chance of me bottoming out is slim, but it only takes once, and this is SoCal, land of culverts and canyons at intersections.

Thanks!

 

How low do the springs drop the car? I have Illuminas and I don't think I've ever bottomed out on the shocks but I'm not 100% sure... I do have bumpstops though and I'd put them on if I were you just for the peace of mind.

 

Sry for nooby question, but what exactly are bumpstops?

 

I would want them.

 

i have heard both sides of this dilema before, but i got progress springs a tokico blues and im slamed and never bottomed out, i think your car it self would hit the ground first

 

I think it would be a rare occasion to bottom them out, but they agreed to put them back in.

 

I'm also running the Illumina's, and even slammed, never once worried about bottoming out. But better safe then sorry,

 

Yea me niether with my Illuminas, but like people say, better safe than sorry. I know for a fact that Blues will bottom out... they're OEM replacement shocks, not performance shocks, and aren't made to be lowered on. My brother's car had some blues and crappy ebay coils that he got free and that he put on to sell the car with, and it bottomed out hard on me once.

 

They put them back in, the ride is nice

 

I used to have H&R Sport springs on my Koni shocks, with the rear shocks set to the lowest perch. They did bottom out from time to time, and eventually my rear bumpstops (which I did not trim) turned to dust. They literally fell apart when I took the suspension apart a few years later.
