Rev9 R9-HS2-023_1 Hyper-Street II Coilover Suspension Lowering Kit, Mono-Tube Shock w/ 32 Click Rebound Setting, Full Length Adjustable, compatible with Toyota Corolla FWD (AE92) 1988-92

It should include instructions with before installing adjustments. Installed and removed the set 3 times to set them up more or less right. The front are very stiff even is the softest setting. The rear sat lower than the front and could not reach same height as the front with adjustment. They seemed to improve stability in turns but still adapting to them.

I must say, for the price, these are some amazing coilovers. The dampening settings are great. When set to full soft, it feels like riding on a cloud if that’s what you prefer. The hard setting is quite stiff as one would expect.Prior to installation, be sure to either remove the spring or undo the preload (measure so you can reset the preload correctly afterwards) and grease the top and bottom spring perches to prevent the spring from binding especially in the front when turning. I had to remove mine after installation to do this; white lithium grease works well. Also be sure to lightly grease or use spray silicone on the threads to prevent corrosion. These were installed on an ae101 Levin.

Funcionan muy bien, pero tuve que abrir más anchos los agujeros para pasar los dos tornillos 🔩 pasadores en la parte de abajo , luego de masificar los agujeros quedaron muy bien en mi Corolla 2009 S.

Instant replacement for stock struts with a stiffer ride and adjustability

Replacement

Note if you haven't been on their site, you may have to get specific bolts only sold by toyota to downsize enough to get a bolt through the holes. Or ream it out like I did, talk about a load of patience though.

On initial install these look and perform amazing for $500 I was thrilled with them but after a year you will have bad coilover clunk and after two years you will have to turn the copression/rebound up so high to keep from bouncing all over the place your teeth will rattle. After extensive research into what I'm going to replace these with I see BC racing and fortune auto being the top brands to go with due to thier warranty, modular construction, repairablity, and reputation. You can bet money that any coilover less than up around a thousand is disposable. If you are investing in coilovers don't make the mistake I did and think there isn't really a difference between these and anything short of a several thousand dollar top of the line set. There are shocks out there for around a thousand that are bulletproof and perform amazing do your research.

I work in a mechanic shop and i thought that since i was on a budget i would try these for a toyota corolla 2016. Later to find out the the front coilovers did not fit! I had to drill new holes for the stock bolts to fit. Also packing caused the items to scratch and damage one another. Save yourself some time and order something else.
