question for new struts

[Brae]

if im getting tokico illuminas and springs, i need bump stops.. but what about bump steer spacers? I'm going to be putting 16's on it so not too sure if they are a mandatory thing? If I should get please let me know, very confused right now.

Bump steer spacers are only of value if you lower the car enough that when you hit a bump in a hard corner it compresses the suspension and the wheel toes out. In a Z this is generally caused by the tie rod and control arm being at different angles. If you want to get technical the bump steer spacers don't actually change the bumpsteer they just make it less noticeable by changing the roll center of the car (some great reading over on Hybrid Z). The good news it that for a street driven car it is almost never an issue. For a track car driven at 10/10 it can be. However, I'm running illuminas and lowered coilovers on my track car without bumpsteer spacers and I have not had any issues with unpredictable steering in corners. If I ran at a lumpier track it may be more of an issue.

I run Eibach springs/Tokico dampers without the spacers. I haven't had any issues, i.e. no weaving when hitting irregularities. Make sure you do use bump stops, the progressive polyurethane ones work nicely.

On my 1972 240Z, I installed the Tokico shocks with the Tokico linear 280 springs (cut to length per BetaMotorsports),

had spring compression checked at a spring shop, installed without bump stops, drives and handles like a charm. May

take additional 1/4 turn out of front springs to lower profile, but she's fine as is. Hope this helps
