EP3 Type R

Has anyone experienced 'bump steer' in their lowered EP3? I think this may be the issue I posted way back about my car having sometimes unpredictable steering when cornering spiritedly on slightly bumpy roads and sometimes when on a straight road.

Looking at my tie rods, they are pretty angled too...i'm considering getting the steering arm bracket which raises it about 1 inch higher and should fix the angle abit. Not too keen on the inverted tie rod ends since i've heard many durability problems compared to oem.

i bump steered a bit. got better tires. actually helped a lot

Arghh. Having a horrible experience with a shop over here.
All I wanted was my plm header and rbc manifold installed and its taking them 3 days.
Rang him just then and he made every excuse.

- this header is very dodgy. It's like a jigsaw puzzle.
- these are gunna give you problems over time.
- these will leak. Connections are dodgy.
- the intake is very difficult to install.
- we install toda, skunk2 and other jap brands

Thought I'd help him out at the start and send him a link for instructions on how to move the rad support forward to fit the intake. It was an eBay link. He said " if I knew it wad a eBay intake, I wouldn't of said yes"

Apologise for my rant. Any experienced any problems and real difficulties running these or installing? I may be wrong when I accuse them of being a horrible garage

you might want to get todds tie rods instead of replacing the ends, more costly but more worth it in the end as it would help improve your turning circle + the ends are adjustable so you can wind them in and reuse the OEM ones which i find personally better then t1r's inverted ends

exactly what I said

Probably gunna get the header spot welded or something as Ive read that the test pipe donut gasket sometimes leaks when the engine is under load. But other than that, most people seem to think they are a great, bang for your buck header.

Anyone running roll center adjusters? Is it necessary to fix my bump steer and correct suspension geometry, apparently it should improve handling aswell? I'm reading up on them and I just cant understand the concept of it lol

honda designed the suspension to to work its best at stock geometry. that is with the lca angled down toward the wheel.

when you lower the car a good amount, as you can imagine, the lca tends to angle up toward the wheel. this brings the chassis 'roll centre' further away below the centre of gravity. cant explain how as the rest is mathematics, but this worsens handling.

roll centre adjusters attempt to fix this problem by increasing he length of the ball joint from the knuckle to the lca, in effect bringing it closer to the original downward angle.

i have no feedback on driving the ep3 with and without roll centre adjusters so i cant tell you how much affect it actually has on the handling

I'm just looking at ways to fix the awkward tie rod angles, I might consider the steering bracket but mines in a pretty extreme angle and the bracket only raises it up by 3.5cm; and roll center adjusters seem pretty expensive for some ball joints lol

roll centres adjusters dont fix the tie rod problem.

i currently just live with the bump steer. driving over bumpy roads, the steering twitch is the least of my worries. im more worried about my spine.

it's raining! hope it doesnt hail! for my car's sake!
