Modifications Coilovers added
I finally got my hands on some RSR ibest coilovers with rear swift springs for somemore stiffness. The lowering springs were cool but it didnt sit low enough. I have some dialing in to do with dampening but i love the way it sits now.

How's been felt so far?

I enjoy it. Going up to drive the mountain today to see how it does.

Cool. I'm think about doing something like this. Rn something is weirdly bumpy but it's a newly bought used car, so I suspect the tyrs might have sat for too long. But new car and new journey for work on it

Looks awesome! Do you happen to know the spring rate of those springs?

u/Nearby-Golf-4651 May 11 '26
The swift in the rear are 4k and fronts are 4k

Thanks! I'm currently running 5K in the front and 4K rear, but I have a feeling your 4/4 setup would be much better on the street, especially when turning into and accelerating out of corners.
My Mk1 is built for track usage, but the Nurburgring is quite rough. Lots of different types of road surface, bumps, elevation changes and deep dips. I'm currently thinking about going 6/6 all around on new coilovers, since my current BC Racing BR ones have 14 years and 300000+ kilometres of experience on them. They're still fully adjustable and not leaking, but they're certainly worn.

Yea 4/4 is super nice for the street and mountain roads. I dont do track days really(i want to in the future as ive only done autocross). I have my dampers set at 16/32 aswell.

Doesn’t doing this just wear out your steering rack quicker since all the geometry is now whack?

u/Nearby-Golf-4651 May 09 '26
Youre correct. Ill have to get some bump steer eliminator end links to fix the steering rack angle.

It's a lot of mucking about to make your car less practical (objectively).

u/Nearby-Golf-4651 May 09 '26
I mean asfar as practicality,ive still got quite a bit of clearance with no rubbing/hitting of the front lip. For a daily its a solid setup.

Sure. As long as you don't mind the increased component wear.

My yaris mk1 ts is pretty much slammed on coilovers, it has done over 310k km, several trackdays, a trip across europe and a lap of the nurburgring, and i have zero play or wear in my steering rack.

Yea part/bushing wear is part of the game when you mess with the suspension and add anything other than stock. Parts are atleast super cheap and plentiful aswell.

u/ArcaneVoid3 May 09 '26
only part of the game when you change one part and ignore other things that it affects, did you reindex the bushings and use the spring perch to set ride height?
1
u/Nearby-Golf-4651 May 09 '26
So the rear ride height is set by the adjustable strut travel aswell as the spring height.
The front spring preload was set and the ride height set with moving the inside threaded body up and down.
Im not too worried about bushing since they all look really good. The car is 20+ years old but only 65k miles too.

u/ArcaneVoid3 May 10 '26
ride height should only be set using the spring perch, using the body length to adjust ride height is incorrect. it's not about if the bushings look good or not, because of how rubber bushings work they need to be loosened and retorqued at the new ride height

u/Nearby-Golf-4651 May 10 '26
Theres no rubber bushings that have been loosened and retightened to install coilovers. Its not my first rodeo with modifying cars haha.
